the following will hang the kernel:
root is mounted nfs,
/etc is unionfs'ed so:
# Create a generic memory disk
/sbin/mdmfs -i 4096 -s $1 -M md $2
mount_md 4096 /.etc
mount_unionfs /.etc /etc
mv some-file somefile
and now the system is stuck.
this behaviour is also present in the unpatched unionfs, but would be nice
if it can be fixed.
