[BraLUG] Vortrag oder vielleicht doch ein Workshop

[dominik gausa]

Kleine Skriptsammlung zum gestrigen Vortrag :)

Folgend 4 BaSH Skripte zum entpacken, mounten und chroot, säubern und 
demounten, ISO erzeugen.
Danke nochmal für den Anreiz :)

open.sh
------------------------------------------------
#!/bin/bash
ISO=$1
if ["$ISO" == ""]
then
     echo usage: $0 ISO
     exit 0

echo mounting ...
mkdir mnt
mount -o loop $ISO $PWD/mnt

echo extract ...
mkdir extract-cd
rsync -exclude=/casper/filesystem.squashfs -a mnt/ extract-cd

echo unsquashfs
unsquashfs mnt/casper/filesystem.squashfs
mv squashfs-root edit



mnt.sh
------------------------------------------------------
#!/bin/bash
echo mount n chroot
mount --bind /dev/ mnt/dev
chroot $PWD/edit mount -t proc none /proc
chroot $PWD/edit mount -t sysfs none /sys
chroot $PWD/edit mount -t devpts none /dev/pts
echo going into chroot
chroot $PWD/edit



umnt.sh
-------------------------------------------------------
#!/bin/bash
echo clean N umount sys
chroot $PWD/edit aptitude clean
chroot $PWD/edit umount /proc || umount -lf /proc
chroot $PWD/edit umount /sys
chroot $PWD/edit umount /dev/pts
