I think some of my PW4 ext3 partitions (not the exported /mnt/us) are possibly corrupted?
Is there a way to force it to fsck itself, or do I need to reinstall the current firmware from scratch somehow?

Ahha, should have spotted this invalid entry in /etc/passwd :

messagebus:x:92:92:messagebus:/bin/false

I did a mntroot rw, and added the missing home directory field and all it well
