Yes, but read my previous posts. I consider the -n and -f mount options to
be a kludge. There is a chicken and egg problem and the workaround is a
kludge. The list of mounted file systems should be maintained by the
kernel IMHO, since the kernel has to know them in any case.

Mouting root read/write too early is even worse. That's no problem
since Suse waits for root fs to be checked before remounting rw. But Suse
has otehr problems when you want to maximize sharing on diskless systems
(init scripts in /sbin for one).

BTW: what is the minimum RAM to run Liunx/PPC these days ? My smallest
(quasi embedded) machines have 16Mb and I hope to keep these running for
at least 5 to 7 more years.
