What type of filesystem is /home?

Is there anything running on your system (outside the chroot) which
has files/directories open inside the chroot?  Is there anything
inside which is running despite the 15killproc script having been
run?

Does lsof report any processes with open file descriptors in the
chroot?  (Could also be the process cwd.)


Thanks,
Roger
