AutoInstall by Progeny!

An AutomatedInstallation tool for Debian.

Bought to you by CraigBox and NeilFenemor with help from JohnMcPherson and DanielLawson

autoinstall depends far too much on having a 1720Kb floppy disc around - so lets blow that away and use a CDRW.

Run make-autoinst-initrd(1) to get your linux and initrd.gz file. This is the end of the involvement with the tools that are provided for autoinstall.

Make a conf dir, copy the examples from /usr/share/doc/autoinstall/ into it. Run autoinst-read-debconf debconf.cfg in this directory to backup your debconf database.

(cd conf && tar cf - . | gzip -9) > conf.tgz

Go get isolinux - part of the syslinux(1) suits - and get it to boot your kernel and initrd file.

I recommend using isolinux-debug.bin until you get things working right - apt-get(8) source syslinux, and then make isolinux-debug.

Create a cdrom/ directory somewhere. Create a cdrom/isolinux/, put isolinux{-debug}.bin in there. Create an cdrom/isolinux/isolinux.cfg file with your lilo(8)-like boot options - you can just use

timeout 100 default linux initrd=initrd.gz prompt 1

Copy your kernel (linux) and initrd (initrd.gz) into the cdrom/isolinux/ directory.

Copy conf.tgz into the cdrom/ directory; it will be mounted off the CD when the system boots off it.

In the cdrom/ directory, issue

mkisofs -o ../bootcd.iso -b isolinux/isolinux.bin -c isolinux/boot.cat \

• no-emul-boot -boot-load-size 4 -boot-info-table .

Now cdrecord that baby and watch things fly.

(Note: You'll need to change linuxrc inside your initrd, to get to mount your data off /cdrom instead of /dev/fd0u1720, unless you want to use a disk as well (whats the point, really?) It's in /usr/lib/autoinstall.)

Search for autoinst_config_drive = "/dev/fd0u1720" and replace with

autoinst_config_drive = "/dev/hdc" autoinst_config_fstype = "iso9660"

Kernel 2.4 keeps its modules somewhere else: a patch for /usr/lib/autoinstall/mkmodules
