I just committed a patch to mount (thanks to Dave Cinege) that
makes commands such as 'mount /proc' and 'mount -o remount,rw /'
so that they now work.

BusyBox does have the "-f" option, but it was not working properly.
I just fixed it and the fix is now in CVS.

BTW, since you seem to be using the /etc/mtab file (rather then making a
symlink to /proc/mounts) you will want to make sure that you have turned on
BB_FEATURE_MOUNT_MTAB_SUPPORT in busybox.def.h.

Good luck,
