Environment variables to configure boot/root/rescue images

General options

cache=1|2|4

cache the rpms we use, it is actually a bitmask; the most useful value is 4, which will cache the unpacked rpm in a separate directory
debug=ignore

ignore noncritical errors
debug=account

create disk usage statistics, stored in tmp/<image_name>.size
dist=8.1, dist=8.1-i386+kde

build for this release
suserelease=8.0

obsolete, equivalent to dist=
kernel=<kernel rpm>

give kernel package name explicitly
theme=<theme>

select this theme (default: theme=SuSE)
themes=<list of themes>

list of supported themes, support all if empty

uncompressed_root=1

build uncompressed image
keeproot=1

don't rebuild everything, just recreate (copy the cached tree and compress) the last image (useful to speed up testing)
filelist=foo

build using foo.file_list
nolibs=1

no ldconfig check
imagetype=foo / imagetype=foo.gz / imagetype=none

use foo as filesystem for image (.gz: and compress with gzip); none: don't create an image
imagename=foo

use tmp/foo & image/foo as temp dir & final image
tmpdir=foo

use foo instead of tmp/root

keeprescue=1

don't rebuild everything, just recreate (copy the cached tree and compress) the last image (useful to speed up testing)
filelist=foo

build using foo.file_list
imagetype=foo / imagetype=foo.gz / imagetype=none

use foo as filesystem for image (.gz: and compress with gzip) none: don't create an image
imagename=foo

use tmp/foo & image/foo as temp dir & final image
tmpdir=foo

use foo instead of tmp/rescue

initrd_fs=<fstype>

use fstype for initrd (default: ext2)
initramfs=1

build initramfs
linuxrc=<absolute_filename>

use the specified linuxrc (taken from the running system!)
mkdevs=1

compress device tree
initrd=small|large

build a small (for 1.44MB boot images) or large (no size limit) version
keepinitrd=1

don't rebuild everything, just recreate (copy the cached tree and compress) the last image (useful to speed up testing)
nousb=1

don't add usb modules to initrd
nopcmcia=1

don't add the /etc/pcmcia tree to initrd
fewkeymaps=1

just english, french and german maps
bootsplash=0|modules1

don't add bootsplash or add splash to modules disk 1 (default is to add it to boot image)
initrd_name=<name>

[default: initrd] name of the final initrd image
with_smb=1

add smb support
with_gdb=1|2

create an initrd with gdb; if with_gdb=2 start linuxrc from gdb
liveeval=1

create an initrd for LiveEval
lang=cs_CZ

[only with liveeval=1] special czech version
extramod=<module>

add <module> to initrd; only one module allowed (useful for testing only)

boot=small|hd|large|isolinux

the boot image type we should create; small is a 1.44MB image, hd for boot CD with hd emulation, isolinux for a CD with 'no emulation'; large is mainly for ia64 (the image is basically just a dos partition)
bootlogo=1|0

whether to add the graphical boot logo; if unset, the logo will not be added for 'boot=small'
memtest=yes|no

whether to add memtest; if unset, memtest will not be added for 'boot=small'
initrd_name=<name>

[default: initrd] name of the initrd image we should add; this will be the name on the boot image and the name referenced in syslinux.cfg, too
noinitrd=<name>

[only with 'boot=small'] do not add the initrd <name> to the boot image, unless it fits on it; the initrd name on the boot image is 'small'; the name in syslinux.cfg is not adjusted to <name>
use_k_inst=1

use kernel image from k_inst for booting
fastboot=1

don't use syslinux' '-s' option for floppies
liveeval=1

liveeval bootloader config
is_dvd=1

create dvd boot config (32/64 bit dual boot)
with_floppy=1

create boot disks, too (i386, x86_86 only)

modules=<number>

build module disk <number>; Note: module disk #1 has the initrd on it, so you must build the initrd explicitly before!
