Thank you for this FAST help. The problem was really inside inittab. I would never have checked that file. The following line does not belong there: null::sysinit:/bin/mount -o remount,rw / I commented it out and everything is the way it should be. Only question is, why did it get into that file ever at all? Thank you a whole lot!
