directory is mounted RW. You may store there everything you want and then use preboot or postboot scripts to copy them after a reboot.
The problem is that the weird device names that zeroshell uses doesn’t work very well when I have to rmmod and then insmod the ethernet drivers. I think I got enough of a hint from:
to do what I want. At this point I am getting a kernel panic at boot (VFS can’t find root) but I believe this can easily be solved by copying the ahci and ata_piix modules (my chipset should use one of those) to the initrd.gz image file.
