I need a bootable BT cdrom with a running SSH Server.
Does anyone know how to alter the config in the ISO Image?

I read about making the sshd init script executable, but I don't know how to
mount/alter the .lzm files.

EDIT: Figured it out.

For those looking for this:
- Extract etc.lzm with base/tools/lzm2dir
- cd into etc/rc.d
- chmod +x rc.sshd
- Pack the dir again to etc.lmz with base/tools/dir2lzm
- Replace the original in the iso (either manually in linux or so, or use sth like winiso in windows)
