[linux-lvm] lvmcreate_initrd don't find module lvm.o

[Chris Worley]

That's not a problem if lvm is built into your kernel (it won't need 
the module).

I found that my lvmcreate_initrd (w/ SuSE 7.0) was missing "mount", 
"umount", and "/proc".  Modify the script to include these, if necessary.

Note, also, when creating the initrd, the current system has to be 
booted with 8MB ramdisks (either specified to lilo or in the kernel 
build).
