Slitaz is a very small (base is 8mb) and highly configurable “live cd” distribution this makes it perfect for use in a rescue environment. The following steps were used to create a ‘rescue mode’ version of Slitaz which can be rapidly booted via PXE and includes RAID kernel modules, networking + SSH.
All of these steps were completed on a virtual machine booted using Slitaz 3.0 base (available from http://mirror.slitaz.org/iso/3.0/flavors/slitaz-3.0-base.iso). When the machine first boots you should login as root (password root) and start ssh (dropbear) then you can complete the instructions via an SSH client.
sed -i 's/DROPBEAR_OPTIONS.*/DROPBEAR_OPTIONS=""/' /etc/daemons.conf /etc/init.d/dropbear start
Now SSH into the VM and copy/adjust/paste the rest of the instructions.
Get base flavor to work from
tazlito extract-flavor base cp -a /home/slitaz/flavors/base /home/slitaz/flavors/rescue cd /home/slitaz/flavors/rescue
Update metadata
sed -i s/base/rescue/ receipt sed -i 's/Minimal set of packages to boot/base + rescue customisations/' receipt
Add useful packages
echo lvm2 >> packages.list echo nano >> packages.list
Create directory for custom config
mkdir -p rootfs/etc
Allow root logins
cat /etc/daemons.conf | sed 's/DROPBEAR_OPTIONS.*/DROPBEAR_OPTIONS=""/' > rootfs/etc/daemons.conf
Run ssh on boot
cat /etc/rcS.conf | sed 's/RUN_DAEMONS="/RUN_DAEMONS="dropbear /' > rootfs/etc/rcS.conf
Use interface on private network
cat /etc/network.conf | sed s/eth0/eth1/ > rootfs/etc/network.conf
Set root passwd
passwd deluser tux cp /etc/shadow rootfs/etc
Install toolchain and kernel source
for i in slitaz-toolchain ncurses-dev perl linux-source; do tazpkg get-install $i; done
Enable storage kernel modules
cd /usr/src/linux echo CONFIG_MEGARAID_SAS=m >> .config echo CONFIG_SCSI_3W_9XXX=m >> .config
Build Slitaz package with the new kernel image and modules
make tazpkg
Copy newly built package into local repo (Note: The filename change is important s/slitaz-/)
mkdir /home/slitaz/packages cp /usr/src/linux/linux-slitaz-2.6.30.6.tazpkg /home/slitaz/packages/linux-2.6.30.6.tazpkg
Create ISO
tazlito pack-flavor rescue tazlito get-flavor rescue.flavor tazlito gen-distro
Copy the kernel and filesystem
scp /home/slitaz/distro/rootcd/boot/rootfs.gz server:/var/www/html/ipxe/rescue scp /home/slitaz/distro/rootcd/boot/vmlinuz-2.6.30.6-slitaz server:/var/www/html/ipxe/rescue
