Modifying Keyboard layout in BootCD

Beitrag von PeterDR »

Hello,

I'm from Belgium and looking for a way to modify the OPSI 4.2 BootCD in such a way so we can use the Belgium keyboard layout : "be-latin1" and to pre-populate the user- and password needed to get the netboot product list.

We cannot use PXE-boot in our environment, so I am forced to modify the BootCD-ISO and boot the cliënts from a USB-stick.

I'm using the ISO "opsi4.2.0-client-boot-cd_20220525.iso"

I've done this modification in the past with OPSI 4.1 (by extracting miniroot-x64.bz2 and making some changes in "./etc/init.d/opsi" and "./usr/local/bin/master.py"), but the OPSI 4.2 BootCD has a different structure so I can't reproduce these steps.

I've noticed that "miniroot-x64.bz2" is replaced by "miniroot-x64.zstd" and that "master.py" is replaced by the - for me - non-editable file "master". So that's a dead end for me.

Also, As soon I extract and modify the "miniroot-x64.zstd" file', the BootCD cannot start the "Logging Service" anymore and becomes unusable.

So, is there anyway to pass-thru the Language and User-account settings by modifying for example "/boot/grub/grub.cfg" or can someone give me the proper commands needed to unpack "miniroot-x64.zstd" and the file "miniroot-x64" therein ?

thanks in advance for your answers

Hi

You should be able to add additional keyboard layouts in the grub.cfg of the iso without extracting the bootimage. Best thing is to dd it on a USB Stick and then edit the grub.cfg directly

However:
to unpack the new bootimage use the following commands

Code: Alles auswählen

mv miniroot-x64.zstd miniroot-x64.zst
unzstd miniroot-x64.zst
cpio -idm < miniroot-x64
Do your changes
repack within a chroot environment:

Code: Alles auswählen

umount -lf sysfs
umount -lf devpts
umount -lf udev
umount -lf proc
find . | grep -va miniroot-x64.zstd | cpio -o -H newc | zstd -19 > miniroot-x64.zstd

Mathias
