The problem is cupsd. Doing an 'lsof +L1':

COMMAND PID USER   FD   TYPE DEVICE SIZE/OFF NLINK   NODE NAME             
                                                                    
cupsd   825 root    8r   REG    8,1     1392     0 132009 /etc/passwd (deleted)

Stopping cups service and re-mounting as 'ro' now works.

I need cups, so is there a way around this?

Thanks,
