Hi, taking advice from other threads, I added an ps and lsof commands to the umountroot script just before the root remount command. The result is attached. As you can see the only non-kernel/init programs running are rc, S60umountroot and plymouthd. Thou I couldn't find in the lsof which is the open file that makes / busy, I agree that plymouthd shouldn't be running at this stage.
Hope this helps with debugging. My system is not clean install, upgraded several times, maybe this is the source of the problem.
