prelink -amfR: bug exist else: no bug fs reiserfs OR lvm OR soft raid... (In reply to comment #0) just add telinit u after sync; sync in the /etc/init.d/mount-ro enjoy I'm sorry for the late reply; neither prelink nor adding "telinit u" in the init script made a difference. As far as I can see you suspect that some process is still having a handle open on the / mount. Wouldn't it make sense to do some kind of logging or debugging to see which one? I've added now a simple "ps -ef f > /ps.log" to /lib/rc/sh/rc-mount.sh (right before the "failed because we are using" line).

This is what I get: Which version of linux-utils are you running? Add this command in place of your ps command; I think it will give better information about which processes are using the file system. fuser -v $f_opts "$mnt" > /fuser.log 2>&1 What does that output look like?
