68 If the standard boot-from-CD install method doesn't work for you (or you just
69 don't like it), help is now here. This document serves to provide a repository
70 of alternative Gentoo Linux installation techniques to those who need them.
71 Or, if you prefer, it serves as a place to put your wacky installation methods.
72 If you have an installation method that you yourself find useful, or you have
73 devised an amusing way of installing Gentoo, please don't hesitate to write
74 something up and post it on <uri link="http://bugs.gentoo.org">Bugzilla</uri>.

82 <title>Booting the Install CD with Smart BootManager</title>
83 <section>
84 <body>
85
86 <p>
87 Download Smart BootManager available from
88 <uri>http://btmgr.sourceforge.net/download.html</uri>.
89 Linux source or binary format and windows .exe versions are available as well
90 as many language packs. However, at this time, the preferred method would be to
91 use the binary format, as the source will not compile with newer versions of
92 NASM.
93 </p>
94
95 <p>
96 Either compile the package from source or just grab the binary. There are
97 several options that can be utilized while creating your boot floppy, as seen
98 below.
99 </p>
100
101 <pre caption="Smart BootManager Options">
102 sbminst [-t theme] [-d drv] [-b backup_file] [-u backup_file]
103
104 -t theme select the theme to be used, in which the theme could be:
105 us = English theme de = German theme
106 hu = Hungarian theme zh = Chinese theme
107 ru = Russian theme cz = Czech theme
108 es = Spanish theme fr = French theme
109 pt = Portuguese theme
110
111
112 -d drv set the drive that you want to install Smart BootManager on;
113 for Linux:
114 /dev/fd0 is the first floppy driver,
115 /dev/hda is the first IDE harddisk driver.
116 /dev/sda is the first SCSI harddisk driver.
117 for DOS:
118 0 is the first floppy drive
119 128 is the first hard drive;
120
121 -c disable CD-ROM booting feature;
122
123 -b backup_file backup the data that will be overwritten for
124 future uninstallation;
125
126 -u backup_file uninstall Smart BootManager, should be used alone;
127
128 -y do not ask any question or warning.
129 </pre>
130
131 <pre caption="Using sbminst to build the boot floppy">
132 # <i>sbminst -t us -d /dev/fd0</i>
133 </pre>
134
135 <note>
136 Replace <path>fd0</path> with your respective floppy device name if yours is
137 different.
138 </note>
139
140 <p>
141 Now simply place the floppy in the floppy drive of the computer you'd like to
142 boot the Install CD on, as well as placing the Install CD in the CD-ROM and boot
143 the computer.
144 </p>
145
146 <p>
147 You'll be greeted with the Smart BootManager dialog. Select your CD-ROM and
148 press ENTER to boot the Install CD. Once booted proceed with the standard
149 installation instructions.
150 </p>

162 <title>Knoppix Installation</title>
163 <section>
164 <body>
165
166 <note>
167 Knoppix is only available for x86 users.
168 </note>
169
170 <!-- this works with knoppix 3.6+ and gentoo 2004.3, 2005.0-->
171
172 <p>
173 Booting from the <uri link="http://www.knoppix.org/">Knoppix</uri> LiveCD is a
174 way to have a fully functional system while you're compiling Gentoo. Tux Racer
175 will help you pass the time while you wait, and you can use OpenOffice for
176 work.
177 </p>
178
179 <warn>
180 Be aware that if you save anything in Knoppix's home directory while waiting
181 for your Gentoo system to install, it will not be available when you reboot
182 into Gentoo. Be sure to save important files on the hard disk or on some other
183 computer!
184 </warn>
185
186 <p>
187 Boot from the Knoppix CD. If you have Knoppix 3.6-3.8.2, you will need to
188 specify <c>knoppix26</c> as a boot option to load a 2.6 kernel. If you miss
189 this step, when you <c>chroot</c>, you will recieve an error saying that your
190 kernel is too old. If, however, you have Knoppix 3.9+, this step is
191 unnecessary, since the 2.6 kernel is default.
192 </p>
193
194 <p>
195 By default Knoppix boots into a KDE desktop. Open a <c>konsole</c> and <c>su
196 -</c> so you can change your password. This lets you set the root password for
197 Knoppix. You can now configure <c>sshd</c> for remote login, at your
198 preference.
199 </p>
200
201 <pre caption="Creating the /mnt/gentoo mountpoint">
202 # <i>mkdir /mnt/gentoo</i>
203 </pre>
204
205 <p>
206 At this point, you can pick up with the standard install documentation at <uri
207 link="/doc/en/handbook/handbook-x86.xml?part=1&amp;chap=4">part 4</uri>.
208 However, when you are asked to mount the proc system, issue the following
209 command instead:
210 </p>
211
212 <pre caption="Bind-mounting the proc pseudo filesystem">
213 # <i>mount -o bind /proc /mnt/gentoo/proc</i>
214 </pre>
215
216 <p>
217 Also, know that some of Portage's FEATURES will not work in knoppix. Especially
218 watch out for <c>userpriv</c> and <c>usersandbox</c>. If you find yourself
219 getting errors, it might be wise to disable some or all of the optional
220 features.
221 </p>
222
223 <!--
224 Commenting out due to #78716. If it needs to be restated again, note
225 that some will require to bind-mount it, others don't, and that you have
226 a 50-50 chance of winning the gold strike.
227
228
229 <p>
230 You will also need to bind-mount the device tree to resolve permission issues
231 with various device files.
232 </p>
233
234 < ! - -
235 If this doesn't seem to work, #71901 mentions the following command:
236 mount -o remount,rw,nosuid /dev/hd* /mnt/hd*
237 before all. Looks weird to me, but if this doesn't work, we might want to try
238 that.

251 <title>Diskless install using PXE boot</title>
252 <section>
253 <title>Requirements</title>
254 <body>
255
256 <p>
257 You will need a network card on the diskless client that uses the PXE protocol
258 to boot, like many 3com cards. You will also need a BIOS that supports booting
259 from PXE.
260 </p>
261
262 </body>
263 </section>
264 <section>
265 <title>Server base setup</title>
266 <body>
267
268 <p>
269 Create directories: The first thing to do is to create the directories where
270 your diskless system will be stored. Create a directory called
271 <path>/diskless</path> which houses a directory for each diskless client. For
272 the rest of this howto we'll be working on the client 'eta'.
273 </p>
274
275 <pre caption="Directory setup">
276 # <i>mkdir /diskless</i>
277 # <i>mkdir /diskless/eta</i>
278 # <i>mkdir /diskless/eta/boot</i>
279 </pre>
280
281 <p>
282 DHCP and TFTP setup: The client will get boot informations using DHCP and
283 download all the required files using TFTP. Just emerge DHCP and configure it
284 for your basic needs. Then, add the following on
285 <path>/etc/dhcp/dhcpd.conf</path>.
286 </p>
287
288 <note>
289 This provide a static IP address for the client and the path of a PXE boot
290 image, here <path>pxegrub</path>. You have to replace the MAC address of the
291 Ethernet card of the client and the directory where you will put the client
292 files with the one you use.
293 </note>
294
295 <p>
296 For DHCPd, run <c>emerge dhcp</c> (or any other DHCP server of your choice).
297 Make sure that the correct interface is selected in
298 <path>/etc/conf.d/dhcpd</path>.
299 </p>
300
301 <pre caption="dhcpd.conf">
302 option option-150 code 150 = text ;

308 filename "/eta/boot/pxegrub";
309 }
310 </pre>
311
312 <p>
313 Next you'll need to configure your interface in <path>/etc/conf.d/net</path> so
314 that it doesn't get cleared at bootup. See <path>/etc/conf.d/net.example</path>
315 for more information.

322
323 <p>
324 For TFTP, emerge <c>app-admin/tftp-hpa</c>. In
325 <path>/etc/conf.d/in.tftpd</path>, put the following :
326 </p>
327
328 <pre caption="in.tftpd">

331 INTFTPD_OPTS="-u ${INTFTPD_USER} -l -vvvvvv -p -c -s ${INTFTPD_PATH}"
332 </pre>
333
334 <p>
335 Setup GRUB: To provide PXE booting I use GRUB with the <c>netboot</c> USE flag
336 enabled. Once GRUB is compiled, copy the PXE image to the diskless client's
337 boot directory. Then edit its <path>grub.lst</path> config file.
338 </p>

356 the directory is the one where your diskless client files are located (on the server).</comment>
357 </pre>
358
359 <p>
360 Setup NFS: NFS is quite easy to configure. The only thing you have to do is to
361 add a line on the <path>/etc/exports</path> config file:

368 </pre>
369
370 <p>
371 Update your hosts: One important thing to do now is to modify your
372 <path>/etc/hosts</path> file to fit your needs.

385 <title>Creating the system on the server</title>
386 <body>
387
388 <p>
389 You might want to reboot the server with a Gentoo Install CD, although you can
390 very well continue immediately if you know how to proceed with the Gentoo
391 Installation Instructions from an existing installation. Follow the standard
392 install procedure as explained in the <uri link="/doc/en/handbook/">Gentoo
393 Handbook</uri> BUT with the following differences:
394 When you mount the file system, do the following (where <path>hdaX</path> is
395 the partition where you created the <path>/diskless</path> directory). You do
396 not need to mount any other partitions as all of the files will reside in the
397 <path>/diskless/eta</path> directory.
398 </p>
399
400 <pre caption="Mounting the filesystem">
401 #<i> mount /dev/hdaX /mnt/gentoo</i>
402 </pre>
403
404 <p>
405 Stage tarballs and chroot: This example uses a stage3 tarball. Mount
406 <path>/proc</path> to your diskless directory and chroot into it to continue
407 with the install. Then follow the installation manual until kernel
408 configuration.
409 </p>
410
411 <warn>
412 Be very careful where you extract your stage tarball. You don't want to end up
413 extracting over your existing installation.
414 </warn>
415
416 <pre caption="Extracting the stage tarball">
417 # <i>cd /mnt/gentoo/diskless/eta/</i>
418 # <i>tar -xvjpf /mnt/cdrom/gentoo/stage3-*.tar.bz2</i>
419 # <i>mount -t proc /proc /mnt/gentoo/diskless/eta/proc</i>

422 # <i>env-update</i>
423 # <i>source /etc/profile</i>
424 </pre>
425
426 <p>
427 Kernel configuration: When you do the <c>make menuconfig</c> of your kernel
428 configuration, don't forget to enable the following options with the others
429 recommended into the install howto.
430 </p>
431
432 <pre caption="menuconfig options">

452 Save the kernel in your chrooted <path>/</path> (not in <path>/boot</path>)
453 according to the pxegrub setting defined earlier. Next configure your
454 diskless client's <path>/etc/fstab</path>.

497 <body>
498
499 <p>
500 For the new client to boot properly, you'll need to configure the bios and the
501 network card to use PXE as the first boot method - before CD-ROM or floppy. For
502 help with this consult your hardware manuals or manufacturers website. The
503 network card should get an IP address using DHCP and download the GRUB PXE
504 image using TFTP. Then, you should see a nice black and white GRUB bootmenu
505 where you will select the kernel to boot and press Enter. If everything is ok
506 the kernel should boot, mount the root filesystem using NFS and provide you
507 with a login prompt. Enjoy.

515 <title>Installing Gentoo from an existing Linux distribution</title>
516 <section>
517 <title>Requirements</title>
518 <body>
519
520 <p>
521 In order to install Gentoo from your existing Linux distribution you need to
522 have chroot command installed, and have a copy of the Gentoo installation
523 tarball or ISO you want to install. A network connection would be preferable if
524 you want more than what's supplied in your tarball. (by the way, a tarball is
525 just a file ending in .tbz or .tar.gz). The author used RedHat Linux 7.3 as the
526 "host" operating system, but it is not very important. Let's get started!
527 </p>
528
529 </body>
530 </section>
531 <section>
532 <title>Overview</title>
533 <body>
534
535 <p>
536 We will first allocate a partition to Gentoo by resizing our existing Linux
537 partition, mount the partition, untar the tarball to the partition that is
538 mounted, chroot inside the pseudo-system and start building. Once the bootstrap
539 process is done, we will do some final configuration on the system so as to
540 make sure it boots, then we are ready to reboot and use Gentoo.
541 </p>
542
543 </body>
544 </section>
545 <section>
546 <title>How should we make space for Gentoo?</title>
547 <body>
548
549 <p>
550 The root partition is the filesystem mounted under <path>/</path>. A quick run
551 of <c>mount</c> on my system shows what I am talking about. We well also use
552 <c>df</c> (disk free) to see how much space I have left and how I will be
553 resizing. Note that it is not mandatory to resize your root partition! You
554 could be resizing anything else supported by our resizer, but let's talk about
555 that later.

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

585 Parted is an utility supplied by the GNU foundation, an old and respectable
586 huge project whose software you are using in this very moment. There is one
587 tool, however, that is extremely useful for us at the moment. It's called
588 parted, partition editor and we can get it from
589 <uri>http://www.gnu.org/software/parted/</uri>
590 </p>
591
592 <note>
593 There are other tools for doing resize of partitions as well, but the author is
594 unsure/uninterested whether PartitionMagic(tm) or other software of the kind do
595 the job. It's the reader's job to check them out
596 </note>
597
598 <p>
599 Look up on that page the type of filesystem you want to resize and see if
600 parted can do it. If not, you're out of luck, you will have to destroy some
601 partition to make space for Gentoo, and reinstall back. Go ahead by downloading
602 the software, install it. Here we have a problem. We want to resize our Linux
603 root partition, therefore we must boot from a floppy disk a minimal linux
604 system and use previously-compiled parted copied to a diskette in order to
605 resize <path>/</path>. However, if you can unmount the partition while still
606 in Linux you are lucky, you don't need to do what follows. Just compile parted
607 and run it on an unmounted partition you chose to resize. Here's how I did it
608 for my system.
609 </p>
610
611 <impo>
612 Make sure that the operations you want to do on your partition are supported by
613 parted!
614 </impo>
615
616 <p>
617 Get the mininux boot/root disk (a 2.4-powered mini Linux distribution on a
618 floppy - free of charge) from <uri>http://mininux.free.fr/uk/</uri>, create a
619 floppy as suggested in the Documentation that accompanies the software package
620 and insert a new floppy in the drive for the next step.
621 </p>
622
623 <note>
624 Note again that Linux is synonym of "There's one more way to do it". Your
625 objective is to run parted on an unmounted partition so it can do its work. You
626 might use some boot/root diskset other than mininux. You might not even
627 need to do this step at all, ie. you might only have umount the filesystem you
628 want to repartition in your Linux session and run parted on it.

641 We will now proceed with the build of parted. If it's not already downloaded
642 and untarred, do so now and <c>cd</c> into the corresponding directory. Now run
643 the following set of commands to build the utility and copy it to your floppy
644 disk.
645 </p>
646
647 <pre caption="Building the utility floppy">
648 # <i> mkdir /floppy; mount -t minix /dev/fd0 /floppy &amp;&amp;
649 export CFLAGS="-O3 -pipe -fomit-frame-pointer -static" &amp;&amp; ./configure
650 &amp;&amp; make &amp;&amp; cp parted/parted /floppy &amp;&amp; umount /floppy </i>
651 </pre>
652
653 <p>
654 Congratulations, you are ready to reboot and resize your partition. Do this
655 only after taking a quick look at the parted documentation on the GNU website.
656 The resize should take under 30 minutes for the largest hard-drives, be
657 patient. Reboot your system with the mininux boot disk (just pop it inside),
658 and once you are logged in, switch the disk in the drive with your utility disk
659 we have created above and type <c>mount /dev/fd0 /floppy</c> to have parted
660 under <path>/floppy</path>. There you go. Run parted and you will be able to
661 resize your partition. Once this lenghty process done, we are ready to have the
662 real fun, by installing Gentoo. Reboot back into your old Linux system for now.
663 The drive you wish to operate on is the drive containing the partition we want
664 to resize. For example, if we want to resize /dev/hda3, the drive is /dev/hda.

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

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