add support for install_root

[glensc]

in linux-live 6.x versions, it was possible to use ROOT directory which is used for building linux live image. i would like that support added back, that way i can build minimal livecd customized for my need (i.e i have packages i want on livecd in temp dir)

also, it would be nice to have support for executing extra scripts when all files have been copied to temp root, i.e to do additional cleanup (in my case i want to shrink /var/lib/rpm contents, which i do not want to do on real /var/lib/rpm)

ps: is there any post on why the versioning schema was changed? i.e 6.x -> 1.8 seems like "downgrade"

I've removed ROOT at all since if you have your root filesystem in a subdirectory, simply unpack livekit there and chroot to it.

Regarding versioning change, 1.8 is the version of Linux Live Kit, which is a completely different project, Linux Live Scripts 6.x is a completely different code.

btw, i found that i can put all *.sb modules to sb/ dir, then build omits scanning filesystem itself

so i created such script (i want to keep kernel dir separate, so i can easily swap kernel without rebuilding whole "OS data")

#!/bin/sh
set -e

cd $(dirname $(readlink -f $0))

. ./.config
. ./livekitlib

OS_SRC=/src
OS_IMAGE=sb/os.sb
KERNEL_IMAGE=sb/kernel-$KERNEL.sb

test -e $OS_IMAGE || \
    mksquashfs $OS_SRC $OS_IMAGE -comp xz -b 512k -e $OS_SRC/lib/modules/*

if [ ! -e $KERNEL_IMAGE ]; then
    t=$(mktemp -d)
    install -d $t/lib/modules
    cp -a /lib/modules/$KERNEL $t/lib/modules
    mksquashfs $t $KERNEL_IMAGE -comp xz -b 512k
    rm -rf $t
fi

perhaps you want to add such script to contrib/ in your distribution? :)
