Any > thoughts or ideas of things I can check? We have : null::sysinit:/bin/mount -o remount,rw / in our default inittab in fs/skeleton/etc/inittab. This should automatically remount the root filesystem as read/write when the system boots. Maybe you are using a different filesystem skeleton ? If not, then edit this line to be : ::sysinit:/bin/mount -o remount,rw / and see if you have error messages.
