Possibly. I can't get it to work with either 2.6.5 or my 2.4 image, though:

valde at peter:~> rpm -q mkinitrd
mkinitrd-3.5.21-1
valde at peter:~> sudo mkinitrd ost.img 2.6.5
No module raid1 found for kernel 2.6.5, aborting.
valde at peter:~> sudo mkinitrd ost.img 2.4.20-20.9custom
pvscan -- LVM driver/module not loaded?

(While I'm running in a 2.6 kernel. module raid1 is not not found for 
2.6.5 because I've built it into the kernel now. I can't be bothered to 
test it as a module at this point)

Wups, what happened with the extra 'w' (4 in all)? It does work, though...

To make as few changes as possible, RH9 users will have to edit it and 
uncomment these lines

INITRDSIZE=4096
INITRDINODES=5000

and run it with the -d option, such as in
# lvm2create_initrd.sh -d 2.6.5

Also, I forgot to mention something weird. If I attempt to boot my old 
2.4 kernel, fsck complains. Booting with kernel option " fastboot" gets 
me past the fsck point, all the way to the final login screen. However, 
in the 2.4 kernel, I no longer have keyboard or mouse support. But I can 
ssh into it from outside. Rebooting again into 2.6 also stops at fsck, 
so the " fastboot" is required *again*. When running in 2.6, I then run 
"lvm vgmknodes" and then it can boot in 2.6 fsck and all - no problemo. 
But it seems I've passed the point of no-return-to-2.4.

Later,

Peter
