19     This HOWTO is meant to be a repository of alternative Gentoo installation
20     methods, for those with special installation needs such as lack of a cdrom
21 gerrynjr 1.14 or a computer that can't boot cds.

33    
34     <p>If the standard boot-from-CD install method doesn't work for you
35     (or you just don't like it),
36     help is now here. This document serves to
37     provide a repository of alternative Gentoo Linux installation techniques
38     to those who need them.
39     Or, if you prefer, it serves as
40     a place to put your wacky installation methods. If you have an
41     installation method that you yourself find useful, or you have devised an
42 gerrynjr 1.14 amusing way of installing Gentoo, please don't hesitate to write something
43 gerrynjr 1.9 up and <mail link="antifa@gentoo.org">send it to me.</mail></p>

54     <body>
55 gerrynjr 1.14 <p>Download Smart BootManager <uri link="http://btmgr.sourceforge.net/index.php3?body=download.html">http://btmgr.sourceforge.net/index.php3?body=download.html</uri>. Linux source or binary format and windows .exe versions are available as well as many language packs. However, at this time, the preferred method would be to use the binary format, as the source will not compile with newer versions of NASM.</p>
56 gerrynjr 1.9
57     <p>Either compile the package from source or just grab the binary. There are several options that can be utilized while creating your boot floppy, as seen below.</p>
58    
59     <pre caption="Smart BootManager Options">
60     <i>sbminst [-t theme] [-d drv] [-b backup_file] [-u backup_file]
61    
62     -t theme select the theme to be used, in which the theme could be:
63     us = English theme de = German theme
64     hu = Hungarian theme zh = Chinese theme
65     ru = Russian theme cz = Czech theme
66     es = Spanish theme fr = French theme
67     pt = Portuguese theme
68    
69    
70     -d drv set the drive that you want to install Smart BootManager on;
71     for Linux:
72     /dev/fd0 is the first floppy driver,
73     /dev/hda is the first IDE harddisk driver.
74     /dev/sda is the first SCSI harddisk driver.
75     for DOS:
76     0 is the first floppy drive
77     128 is the first hard drive;
78    
79     -c disable CD-ROM booting feature;
80    
81 gerrynjr 1.14 -b backup_file backup the data that will be overwritten for
82 gerrynjr 1.9 future uninstallation;
83    
84     -u backup_file uninstall Smart BootManager, should be used alone;
85    
86     -y do not ask any question or warning.</i>
87     </pre>
88    
89     <pre caption="Using sbminst to build the boot floppy">
90     # <i>sbminst -t us -d /dev/fd0</i>
91     </pre>
92     <note> Replace fd0 with your repective floppy device name if yours is different. </note>
93     <p>Now simply place the floppy in the floppy drive of the computer you'd like to boot the LiveCD on, as well as placing the LiveCD in the CD-ROM and boot the computer.</p>
94    
95     <p>You'll be greeted with the Smart BootManager dialog. Select your CD-ROM and press ENTER to boot the LiveCD. Once booted proceed with the standard installation instructions.</p>
96    
97     <p>Further information on Smart BootManager may be found at <uri>http://btmgr.sourceforge.net/</uri></p>

105     <section>
106    
107     <body>
108     <p>Booting from the <uri link="http://www.knoppix.org/">Knoppix</uri> LiveCD is a way to have a fully functional linux system while you're compiling Gentoo. Tux Racer will help you pass the time while you wait for bootstrap.</p>
109    
110     <p>Boot from the Knoppix CD. It generally does a really good job of hardware detection. Although, you may have to add some boot options. </p>
111    
112     <p>By default Knoppix boots into a KDE 3.0 desktop. The first thing I did was open a konsole and typed <c>sudo passwd root</c>. This lets you set the root password for Knoppix.</p>
113    
114     <p> Next, I su to root and typed <c>usermod -d /root -m root</c>. This sets user roots home directory to /root (the Gentoo way) from /home/root (the Knoppix way). If you do not do this, then you will receive errors when emerging about "/home/root: not found" or something to that effect.</p>
115    
116 swift 1.16 <p>I then typed <c>exit</c> and then <c>su</c> back into root. This loads the change that was made with the usermod command. At this point, you can pick up with the standard install documentation at step 6. However, when you're asked to mount the proc system, issue the following commands instead: </p>
117    
118     <pre caption = "Bind-mounting two important filesystems">
119     # <i>mount -o bind /proc /mnt/gentoo/proc</i>
120     # <i>mount -o bind /dev /mnt/gentoo/dev</i>

133     <p>Burn a LiveCD iso.</p>

135 gerrynjr 1.14 <p>Get the latest portage snapshot from <uri>http://distro.ibiblio.org/pub/linux/distributions/gentoo/snapshots/</uri> (or your favorite <uri link="http://www.gentoo.org/main/en/mirrors.xml">mirror</uri>). Either place this tarball on an existing partition on the computer your are installing to, or burn it to a CD.</p>
136 gerrynjr 1.9
137     <p>You'll also need a package list for the stage packages. Place the following dl-list.sh script on the same medium as the portage snapshot, you'll need it later.</p>

367 gerrynjr 1.14 <p>Create directories: The first thing to do is to create the directories where your diskless system will be stored. Create a directory called <path>/diskless</path> which houses a directory for each diskless client. For the rest of this howto we'll be working on the client 'eta'.</p>

374    
375 gerrynjr 1.14 <p>DHCP and TFTP setup: The client will get boot informations using DHCP and download all the required files using TFTP. Just emerge DHCP and configure it for your basic needs. Then, add the following on <path>/etc/dhcp/dhcpd.conf</path>.</p>
376 gerrynjr 1.9
377 gerrynjr 1.14 <note>This provide a static IP address for the client and the path of a PXE boot image, here pxegrub. You have to replace the MAC address of the Ethernet card of the client and the directory where you will put the client files with the one you use.</note>

397 gerrynjr 1.14 <p>Setup GRUB: To provide PXE booting I use GRUB. You have to compile it by yourself to enable the PXE image compilation ... but that's quite easy. First, get the latest version of the GRUB source code (<c>emerge -f grub</c> will place the tarball in <path>/usr/portage/distfiles</path>). Copy the tarball to <path>/diskless</path> and then build it to make the pxe capable binary. Once the binary is built, copy it to the diskless client's boot directory. Then edit it's grub.lst config file.</p>

For help with this consult your hardware manuals or manufacturers website. The network card should get an IP address using DHCP and download the GRUB PXE image using TFTP. Then, you should see a nice black and white GRUB bootmenu where you will select the kernel to boot and press Enter. If everything is ok the kernel should boot, mount the root filesystem using NFS and provide you with a login prompt. Enjoy.</p>

516     <section> <title> Requirements </title>
517     <body>
518     <p>In order to install Gentoo from your existing Linux distribution you need to
519     have chroot command installed, and have a copy of the Gentoo installation
520     tarball or ISO you want to install. A network connection would be preferable if
521     you want more than what's supplied in your tarball. (by the way, a tarball is
522     just a file ending in .tbz or .tar.gz). The author used RedHat Linux 7.3 as the
523     "host" operating system, but it is not very important. Let's get started! </p>
524     </body>
525     </section>
526    
527     <section> <title> Overview </title>
528     <body>
529 gerrynjr 1.14 <p>We will first allocate a partition to Gentoo by resizing our existing Linux partition, mount the partition, untar the tarball that is mounted, chroot inside the psuedo-system and start building. Once the bootstrap process is done, we will do some final configuration on the system so as to make sure it boots, then we are ready to reboot and use Gentoo. </p>

533 gerrynjr 1.14 <section> <title> How should we make space for Gentoo? </title>
534 drobbins 1.1 <body>
535    
536     <p>
537 gerrynjr 1.14 The root partition is the filesystem mounted under <path>/</path>. A quick run of mount on my system shows what I am talking about. We well also use df (disk free) to see how much space I have left and how I will be resizing. Note that it is not mandatory to resize your root partition! You could be resizing anything else supported by our resizer, but let's talk about that later.</p>
538 drobbins 1.1
539    
540     <pre caption="Filesystem information">
541     # <i>mount</i>
542     /dev/hdb2 on / type ext3 (rw)
543     none on /proc type proc (rw)

550     </pre>
551    
552 gerrynjr 1.14 <p>As we can see, the partition mounted as <path>/</path> named <path>/dev/hdb2</path> has 2.4 gigabytes free. In my case, I think I will resize it as to leave 400Megs free of space, therefore allocating 2 gigabytes for Gentoo. Not bad, I could have quite some stuff installed. However, think that even one gigabyte is enough for most users. So let's partition this thing! </p>

556     <section> <title> Building parted to resize partition </title>
557     <body>
558     <p>Parted is an utility supplied by the GNU foundation, an old and respectable huge project whose software you are using in this very moment. There is one tool, however, that is extremely useful for us at the moment. It's called parted, partition editor and we can get it from <uri>
559 klieber 1.5 http://www.gnu.org/software/parted/</uri>
560 drobbins 1.1 </p>
561     <note> There are other tools for doing resize of partitions as well, but author
562     is unsure/uninterested whether PartitionMagic(tm) or other software of the kind
563     do the job. It's the reader's job to check them out </note>
564    
565     <p>
566     Look up on that page the type of filesystem you want to resize and see if parted
567     can do it. If not, you're out of luck, you will have to destroy some partition
568 gerrynjr 1.14 to make space for Gentoo, and reinstall back. Go ahead by downloading the
569 drobbins 1.1 software, install it. Here we have a problem. We want to resize our Linux root
570     partition, therefore we must boot from a floppy disk a minimal linux system and
571 gerrynjr 1.14 use previously-compiled parted copied to a diskette in order to resize <path>/</path>.
572 drobbins 1.1 However, if you can unmount the partition while still in Linux you are lucky,
573     you don't need to do what follows. Just compile parted and run it on an
574     unmounted partition you chose to resize. Here's how I did it for my system.
575     </p>
576    
577     <impo> Make sure that the operations you want to do on your partition are
578     supported by parted! </impo>
579    
580     <p> Get tomsrtbt boot/root disk (free of charge) from <uri>
581 gerrynjr 1.14 http://freshmeat.net/tomsrtbt </uri>, create a floppy as suggested in the
582 drobbins 1.1 Documentation that accompanies the software package and insert a new floppy in
583     the drive for the next step. </p>
584    
585     <note> Note again that Linux is synonym of "There's one more way to do it". Your
586     objective is to run parted on an unmounted partition so it can do its work. You
587     might use some other boot/root diskset other than tomsrtbt. You might not even
588     need to do this step at all, that is only umount the filesystem you want to
589     repartition in your Linux session and run parted on it. </note>
590    
591     <pre caption="Utility disk creation">
592     # <i>mkfs.minix /dev/fd0</i>

596     Zonesize=1024
597     Maxsize=268966912
598     </pre>
599    
600     We will now proceed with the build of parted. If it's not already downloaded and untarred, do so now and cd into the corresponding directory. Now run the following set of commands to build the utility and copy it to your floppy disk.
601    
602     <pre caption="Building the utility floppy">
603     # <i> mkdir /floppy; mount -t minix /dev/fd0 /floppy &amp;&amp;
604     export CFLAGS="-O3 -pipe -fomit-frame-pointer -static" &amp;&amp; ./configure
605     &amp;&amp; make &amp;&amp; cp parted/parted /floppy &amp;&amp; umount /floppy </i>
606     </pre>
607    
608     <p>
609     Congratulations, you are ready to reboot and resize your partition. Do this only
610     after taking a quick look at the parted documentation on the GNU website. The
611     resize should take under 30 minutes for the largest hard-drives, be patient.
612     Reboot your system with the tomsrtbt boot disk (just pop it inside), and once
613     you are logged in, switch the disk in the drive with your utility disk we have
614     created above and type mount /dev/fd0 /floppy to have parted under /floppy.
615     There you go. Run parted and you will be able to resize your partition. Once
616     this lenghty process done, we are ready to have the real fun, by installing
617 gerrynjr 1.14 Gentoo. Reboot back into your old Linux system for now. Drive you wish to
618 swift 1.8 operate on is the drive containing the partition we want to resize. For
619     example, if we want to resize /dev/hda3, the drive is /dev/hda

647     minutes. </impo>
648    
649     <p>Once you have resized, boot back into your old linux as described. Then go to

Don't forget to create the <path>/mnt/gentoo</path> directory before proceeding with step 7. In step 8 you have to download the requested stage-tarball as we're not working from a LiveCD.
