[Buildroot] inittab -- mount -o remount,rw / fails

[ANDY KENNEDY]

In inittab, the lines:

# Startup the system
null::sysinit:/bin/mount -o remount,rw /
null::sysinit:/bin/mount -t proc proc /proc

are supposed to remount the filesystem read-write enabled.  In my case
(mounting root via NFS) I don't get an error on console, but I do not
remount /.  So, what happens next is all the first boot stuff (making
the RSA keys, etc) fails.  My fix for this was to mount proc first.

Should mount be able to remount / without proc being mounted? 

If not, perhaps we should change fs/skeleton/etc/inittab to reflect the
below.

# Startup the system
null::sysinit:/bin/mount -t proc proc /proc
null::sysinit:/bin/mount -o remount,rw /


Cheers,
