[uClibc] Linux 2.6 ROMFS vs EXT2

[Christian MICHON]

I did some stuff on romfs 2 years ago. Let me recall...

I think romfs isn't intended to be a initrd.
Initrd stands for "Init Ram Disk". Usually to boot
on a initrd, it must be rw mode.

I'd suggest you keep your romfs for directories that
do not need rw, but can be ro. Typically /usr/X11R6
and /opt which may contain some big software not
needed to boot.

Note that the kernel panic is not complaining about
not being able to rw. Check /proc/filesystems is
romfs able. It's seldom the case unless you
specifically turn it on in kernel config.
