63 If the standard boot-from-CD install method doesn't work for you (or you just
64 don't like it), help is now here. This document serves to provide a repository
65 of alternative Gentoo Linux installation techniques to those who need them.
66 Or, if you prefer, it serves as a place to put your wacky installation methods.
67 If you have an installation method that you yourself find useful, or you have
68 devised an amusing way of installing Gentoo, please don't hesitate to write
69 something up and <mail link="antifa@gentoo.org">send it to me.</mail>

77 <title>Booting the LiveCD with Smart BootManager</title>
78 <section>
79 <body>
80
81 <p>
82 Download Smart BootManager available from
83 <uri>http://btmgr.sourceforge.net/download.html</uri>.
84 Linux source or binary format and windows .exe versions are available as well
85 as many language packs. However, at this time, the preferred method would be to
86 use the binary format, as the source will not compile with newer versions of
87 NASM.
88 </p>
89
90 <p>
91 Either compile the package from source or just grab the binary. There are
92 several options that can be utilized while creating your boot floppy, as seen
93 below.
94 </p>
95
96 <pre caption="Smart BootManager Options">
97 <i>sbminst [-t theme] [-d drv] [-b backup_file] [-u backup_file]
98
99 -t theme select the theme to be used, in which the theme could be:
100 us = English theme de = German theme
101 hu = Hungarian theme zh = Chinese theme
102 ru = Russian theme cz = Czech theme
103 es = Spanish theme fr = French theme
104 pt = Portuguese theme
105
106
107 -d drv set the drive that you want to install Smart BootManager on;
108 for Linux:
109 /dev/fd0 is the first floppy driver,
110 /dev/hda is the first IDE harddisk driver.
111 /dev/sda is the first SCSI harddisk driver.
112 for DOS:
113 0 is the first floppy drive
114 128 is the first hard drive;
115
116 -c disable CD-ROM booting feature;
117
118 -b backup_file backup the data that will be overwritten for
119 future uninstallation;
120
121 -u backup_file uninstall Smart BootManager, should be used alone;
122
123 -y do not ask any question or warning.</i>
124 </pre>
125
126 <pre caption="Using sbminst to build the boot floppy">
127 # <i>sbminst -t us -d /dev/fd0</i>
128 </pre>
129
130 <note>
131 Replace fd0 with your respective floppy device name if yours is different.
132 </note>
133
134 <p>
135 Now simply place the floppy in the floppy drive of the computer you'd like to
136 boot the LiveCD on, as well as placing the LiveCD in the CD-ROM and boot the
137 computer.
138 </p>
139
140 <p>
141 You'll be greeted with the Smart BootManager dialog. Select your CD-ROM and
142 press ENTER to boot the LiveCD. Once booted proceed with the standard
143 installation instructions.

156 <title>Knoppix Installation</title>
157 <section>
158 <body>
159
160 <p>
161 Booting from the <uri link="http://www.knoppix.org/">Knoppix</uri> LiveCD is a
162 way to have a fully functional linux system while you're compiling Gentoo. Tux
163 Racer will help you pass the time while you wait for bootstrap.
164 </p>
165
166 <p>
167 Boot from the Knoppix CD. It generally does a really good job of hardware
168 detection. Although, you may have to add some boot options.
169 </p>
170
171 <p>
172 By default Knoppix boots into a KDE 3.0 desktop. The first thing I did was open
173 a konsole and typed <c>sudo passwd root</c>. This lets you set the root
174 password for Knoppix.
175 </p>
176
177 <p>
178 Next, I <c>su</c> to root and typed <c>usermod -d /root -m root</c>. This sets
179 user roots home directory to /root (the Gentoo way) from /home/root (the Knoppix
180 way). If you do not do this, then you will receive errors when emerging about
181 "/home/root: not found" or something to that effect.
182 </p>
183
184 <p>
185 I then typed <c>exit</c> and then <c>su</c> back into root. This loads the
186 change that was made with the usermod command. Now create the
187 <path>/mnt/gentoo</path> mountpoint using <c>mkdir</c>:
188 </p>
189
190 <pre caption="Creating the /mnt/gentoo mountpoint">
191 # <i>mkdir /mnt/gentoo</i>
192 </pre>
193
194 <p>
195 At this point, you can pick up with the standard install documentation at <uri
196 link="/doc/en/handbook/handbook-x86.xml?part=1&amp;chap=4">part 4</uri>.
197 However, when you're asked to mount the proc system, issue the following
198 command instead:
199 </p>
200
201 <pre caption="Bind-mounting the proc pseudo filesystem">

213
214 <p>
215 Burn a LiveCD iso.
216 </p>
217
218 <p>
219 Get the latest portage snapshot from
220 <uri>http://distro.ibiblio.org/pub/linux/distributions/gentoo/snapshots/</uri>
221 (or your favorite <uri
222 link="http://www.gentoo.org/main/en/mirrors.xml">mirror</uri>). Either place
223 this tarball on an existing partition on the computer your are installing to,
224 or burn it to a CD.
225 </p>
226
227 <p>
228 Follow all instructions of the Gentoo Installation Handbook up to <c>chroot
229 /mnt/gentoo</c> in Chapter 6. If you only have one CD-ROM remember to use the
230 <c>docache</c> option while booting so you can unmount the LiveCD and mount
231 your portage snapshot CD.
232 </p>
233
234 <p>
235 Open a new console (Alt-F2), we will continue with the Install Doc up to
236 running the bootstrap.sh script.
237 </p>
238
239 <warn>
240 Older realeases of the livecd required you to change the password using the
241 <c>passwd</c> command, before logging in manually.
242 </warn>
243
244 <p>
245 Go back to the first console (Alt-F1, without chroot) and mount a second CD on
246 <path>/mnt/gentoo/mnt/cdrom2</path>. Copy the portage tarball from cdrom2 and
247 unpack it to <path>/mnt/gentoo/usr/portage</path>.
248 </p>
249
250 <pre caption="Mount the snapshot cd">
251 # <i>umount /mnt/cdrom</i>
252 # <i>mkdir /mnt/gentoo/mnt/cdrom2</i>
253 # <i>mount /dev/cdroms/cdrom0 /mnt/gentoo/mnt/cdrom2</i>
254 # <i>cp /mnt/gentoo/mnt/cdrom2/portage-$date.tar.bz2 /mnt/gentoo/usr/portage</i>
255 # <i>cd /mnt/gentoo/usr/portage</i>
256 # <i>tar xvjpf portage-$date.tar.bz2</i>
257 </pre>
258
259 <p>
260 Switch back to the F2 console. Now if you try to run bootstrap.sh it will fail
261 because it won't be able to download any files. We will fetch these files
262 somewhere else and put them in /usr/portage/distfiles (on F2 console).
263 </p>
264
265 <p>
266 You need a list of Stage1 packages: glibc, baselayout, texinfo, gettext, zlib,
267 binutils, gcc, ncurses plus their dependencies.
268 </p>
269
270 <note>
271 Note that you need the versions of each package synced with your portage tree.
272 </note>
273
274 <pre caption="Getting the download listing">
275 <comment>(Don't forget the 2 in front of the &gt;)</comment>
276 # <i>emerge -fp glibc baselayout texinfo gettext zlib binutils gcc ncurses 2&gt; stage1.list</i>
277 # <i>mount -t vfat /dev/fd0 /mnt/floppy</i>
278 # <i>cp /mnt/gentoo/stage1.list /mnt/floppy</i>
279 # <i>umount /mnt/floppy</i>
280 </pre>
281
282 <p>
283 Take the floppy to the computer that has fast access. If you take a look at the
284 <path>stage1.list</path> file, you'll see that it provides you with several
285 URLs to download. Sadly, it lists several possible URLs for each package as
286 well, which isn't what you want. Strip all but one of the URLs first:
287 </p>
288
289 <pre caption="Stripping URLs">
290 <comment>(This script is depending on the output format given by emerge which
291 might change in the future without further notice - use with caution!)</comment>
292 # <i>cut -f 1 -d ' ' stage1.list > stage1.download</i>
293 </pre>
294
295 <p>
296 Now use <c>wget</c> to fetch all the listed sources:
297 </p>
298
299 <pre caption="Use wget to grab your source packages">
300 # <i>wget -N -i stage1.download</i>
301 </pre>
302
303 <p>
304 Once you have obtained all the files, take them to the computer and copy them
305 to <path>/mnt/gentoo/usr/portage/distfiles</path>. You will then be able to run
306 <c>bootstrap.sh</c>. Repeat this same wget fetch and place procedure for stage2
307 and 3.

315 <title>Diskless install using PXE boot</title>
316 <section>
317 <title>Requirements</title>
318 <body>
319
320 <p>
321 You will need a network card on the diskless client that uses the PXE protocol
322 to boot, like many 3com cards. You will also need a BIOS that supports booting
323 from PXE.
324 </p>

327 </section>
328 <section>
329 <title>Server base setup</title>
330 <body>
331
332 <p>
333 Create directories: The first thing to do is to create the directories where
334 your diskless system will be stored. Create a directory called
335 <path>/diskless</path> which houses a directory for each diskless client. For
336 the rest of this howto we'll be working on the client 'eta'.
337 </p>
338
339 <pre caption="directory setup">
340 # <i>mkdir /diskless</i>
341 # <i>mkdir /diskless/eta</i>
342 # <i>mkdir /diskless/eta/boot</i>
343 </pre>
344
345 <p>
346 DHCP and TFTP setup: The client will get boot informations using DHCP and
347 download all the required files using TFTP. Just emerge DHCP and configure it
348 for your basic needs. Then, add the following on
349 <path>/etc/dhcp/dhcpd.conf</path>.
350 </p>
351
352 <note>
353 This provide a static IP address for the client and the path of a PXE boot
354 image, here pxegrub. You have to replace the MAC address of the Ethernet card
355 of the client and the directory where you will put the client files with the
356 one you use.
357 </note>
358
359 <pre caption="dhcp.conf">
360 option option-150 code 150 = text ;
361 host eta {
362 hardware ethernet 00:00:00:00:00:00;

364 option option-150 "/eta/boot/grub.lst";
365 filename "/eta/boot/pxegrub";
366 }
367 </pre>
368
369 <p>
370 For TFTP, emerge <c>app-admin/tftp-hpa</c>. In
371 <path>/etc/conf.d/in.tftpd</path>, put the following :
372 </p>
373
374 <pre caption="in.tftpd">
375 INTFTPD_PATH="/diskless"
376 INTFTPD_USER="nobody"
377 INTFTPD_OPTS="-u ${INTFTPD_USER} -l -vvvvvv -p -c -s ${INTFTPD_PATH}"
378 </pre>
379
380 <p>
381 Setup GRUB: To provide PXE booting I use GRUB. You have to compile it by
382 yourself to enable the PXE image compilation ... but that's quite easy. First,
383 get the latest version of the GRUB source code (<c>emerge -f grub</c> will
384 place the tarball in <path>/usr/portage/distfiles</path>). Copy the tarball to
385 <path>/diskless</path> and then build it to make the pxe capable binary. Once
386 the binary is built, copy it to the diskless client's boot directory. Then edit
387 it's grub.lst config file.
388 </p>
389
390 <pre caption="grub setup">

415

417 Setup NFS: NFS is quite easy to configure. The only thing you have to do is to
418 add a line on the <path>/etc/exports</path> config file :

445 <p>
446 You might want to reboot the server with a Gentoo LiveCD, although you can
447 very well continue immediately if you know how to proceed with the Gentoo
448 Installation Instructions from an existing installation. Follow the standard
449 install procedure as explained in the Gentoo Install Howto BUT with the
450 following differences:
451 When you mount the file system, do the following (where hdaX is the partition
452 where you created the /diskless directory). You do not need to mount any other
453 partitions as all of the files will reside in the <path>/diskless/eta</path>
454 directory.
455 </p>
456
457 <pre caption="mounting the filesystem">
458 #<i> mount /dev/hda3 /mnt/gentoo</i>
459 </pre>
460
461 <p>
462 Stage tarballs and chroot: This example uses a stage3 tarball. Mount
463 <path>/proc</path> to your diskless directory and chroot into it to continue
464 with the install. Then follow the installation manual until kernel
465 configuration.
466 </p>
467
468 <warn>
469 Be very careful where you extract your stage tarball. You don't want to end up
470 extracting over your existing installation.
471 </warn>
472
473 <pre caption="extracting the stage tarball">

484 Kernel configuration: When you do the <c>make menuconfig</c> of your kernel
485 configuration, don't forget to enable the following options with the others
486 recommended into the install howto.

557 For the new client to boot properly, you'll need to configure the bios and the
558 network card to use PXE as the first boot method - before CD-ROM or floppy. For
559 help with this consult your hardware manuals or manufacturers website. The
560 network card should get an IP address using DHCP and download the GRUB PXE
561 image using TFTP. Then, you should see a nice black and white GRUB bootmenu
562 where you will select the kernel to boot and press Enter. If everything is ok
563 the kernel should boot, mount the root filesystem using NFS and provide you
564 with a login prompt. Enjoy.

572 <title>Installing Gentoo from an existing Linux distribution</title>
573 <section>
574 <title>Requirements</title>

576
577 <p>
578 In order to install Gentoo from your existing Linux distribution you need to
579 have chroot command installed, and have a copy of the Gentoo installation
580 tarball or ISO you want to install. A network connection would be preferable if
581 you want more than what's supplied in your tarball. (by the way, a tarball is
582 just a file ending in .tbz or .tar.gz). The author used RedHat Linux 7.3 as the
583 "host" operating system, but it is not very important. Let's get started!

592 <p>
593 We will first allocate a partition to Gentoo by resizing our existing Linux
594 partition, mount the partition, untar the tarball that is mounted, chroot
595 inside the psuedo-system and start building. Once the bootstrap process is
596 done, we will do some final configuration on the system so as to make sure it
597 boots, then we are ready to reboot and use Gentoo.

607 The root partition is the filesystem mounted under <path>/</path>. A quick run
608 of mount on my system shows what I am talking about. We well also use df (disk
609 free) to see how much space I have left and how I will be resizing. Note that
610 it is not mandatory to resize your root partition! You could be resizing
611 anything else supported by our resizer, but let's talk about that later.
612 </p>

614 <pre caption="Filesystem information">
615 # <i>mount</i>
616 /dev/hdb2 on / type ext3 (rw)
617 none on /proc type proc (rw)
618 none on /dev/pts type devpts (rw,gid=5,mode=620)
619 none on /dev/shm type tmpfs (rw,nodev,nosuid,noexec)

625
626 <p>
627 As we can see, the partition mounted as <path>/</path> named
628 <path>/dev/hdb2</path> has 2.4 gigabytes free. In my case, I think I will
629 resize it as to leave 400Megs free of space, therefore allocating 2 gigabytes
630 for Gentoo. Not bad, I could have quite some stuff installed. However, think
631 that even one gigabyte is enough for most users. So let's partition this thing!

637 <title>Building parted to resize partition</title>
638 <body>
639
640 <p>
641 Parted is an utility supplied by the GNU foundation, an old and respectable
642 huge project whose software you are using in this very moment. There is one
643 tool, however, that is extremely useful for us at the moment. It's called
644 parted, partition editor and we can get it from
645 <uri>http://www.gnu.org/software/parted/</uri>
646 </p>
647
648 <note>
649 There are other tools for doing resize of partitions as well, but author is
650 unsure/uninterested whether PartitionMagic(tm) or other software of the kind do
651 the job. It's the reader's job to check them out
652 </note>
653
654 <p>
655 Look up on that page the type of filesystem you want to resize and see if
656 parted can do it. If not, you're out of luck, you will have to destroy some
657 partition to make space for Gentoo, and reinstall back. Go ahead by downloading
658 the software, install it. Here we have a problem. We want to resize our Linux
659 root partition, therefore we must boot from a floppy disk a minimal linux
660 system and use previously-compiled parted copied to a diskette in order to
661 resize <path>/</path>. However, if you can unmount the partition while still
662 in Linux you are lucky, you don't need to do what follows. Just compile parted
663 and run it on an unmounted partition you chose to resize. Here's how I did it
664 for my system.
665 </p>
666
667 <impo>
668 Make sure that the operations you want to do on your partition are supported by
669 parted!
670 </impo>
671
672 <p>
673 Get tomsrtbt boot/root disk (free of charge) from
674 <uri>http://freshmeat.net/tomsrtbt </uri>, create a floppy as suggested in the
675 Documentation that accompanies the software package and insert a new floppy in
676 the drive for the next step.
677 </p>
678
679 <note>
680 Note again that Linux is synonym of "There's one more way to do it". Your
681 objective is to run parted on an unmounted partition so it can do its work. You
682 might use some other boot/root diskset other than tomsrtbt. You might not even
683 need to do this step at all, that is only umount the filesystem you want to
684 repartition in your Linux session and run parted on it.
685 </note>

697 We will now proceed with the build of parted. If it's not already downloaded
698 and untarred, do so now and cd into the corresponding directory. Now run the
699 following set of commands to build the utility and copy it to your floppy disk.
700 </p>
701
702 <pre caption="Building the utility floppy">
703 # <i> mkdir /floppy; mount -t minix /dev/fd0 /floppy &amp;&amp;
704 export CFLAGS="-O3 -pipe -fomit-frame-pointer -static" &amp;&amp; ./configure
705 &amp;&amp; make &amp;&amp; cp parted/parted /floppy &amp;&amp; umount /floppy </i>
706 </pre>
707
708 <p>
709 Congratulations, you are ready to reboot and resize your partition. Do this
710 only after taking a quick look at the parted documentation on the GNU website.
711 The resize should take under 30 minutes for the largest hard-drives, be
712 patient. Reboot your system with the tomsrtbt boot disk (just pop it inside),
713 and once you are logged in, switch the disk in the drive with your utility disk
714 we have created above and type mount /dev/fd0 /floppy to have parted under
715 /floppy. There you go. Run parted and you will be able to resize your
716 partition. Once this lenghty process done, we are ready to have the real fun,
717 by installing Gentoo. Reboot back into your old Linux system for now. Drive you
718 wish to operate on is the drive containing the partition we want to resize. For
719 example, if we want to resize /dev/hda3, the drive is /dev/hda
720 </p>

746 Be patient! The computer is working! Just look at the hardware LED on your case
747 to see that it is really working. This should take between 2 and 30 minutes.

751 Once you have resized, boot back into your old linux as described. Then go to
752 <uri link="/doc/en/handbook/handbook-x86.xml?part=1&amp;chap=4">The Gentoo
753 Handbook: Preparing the Disks</uri> and follow the instructions. When
754 chrooting, use the following command to flush your environment:
