Right - with the following patch to fs.py the F7 kernel won't panic
anymore, and a basic F8 will boot. The mkfs tweak is probably
unneeded, the main difference seems to come from -no-sparse:

On F7 - my actual target ATM - the problem is not gone through. Init
is dropping me to a panic shell, and I cannot figure out how to get
something I can mount there. When I get dropped in the shell, lsmod
makes it seem like no interesting modules have been loaded.
modprobe-ing libata, cdrom and other modules works. I don't know the
major/minor numbers enough to mknod my way around here.

So I suspect of the initrd, but I am unsure of what to do next. The
mayflower initrd seems to work though it does  throw some (IMO)
meaningless errors - complaining about old module names that are not
relevant to the 2.6.23 kernel I have:

Building an initramfs at /boot/initrd-2.6.23.1-21.fc7.img for kernel
2.6.23.1-21.fc7
FATAL: Module ide_cd not found.
FATAL: Module =ata not found.
FATAL: Module usbhid not found.
FATAL: Module ieee1394 not found.
Done; initramfs is 4.2M.

any more hints on this track?

TIA,




martin
