Arch hanging at shutdown

For personal reference..

A default Arch install hangs at "Unmounting Filesystems" when attached to a cifs mounted device.
As far as I understand it tries to unmount this cifs device when network is already gone. This seems to result in an endless "wait for response" loop.
A change of code in /etc/rc.shutdown fixed it for me..
Change the following line from..
<pre>/bin/umount -a -r -t noramfs,notmpfs,nosysfs,noproc</pre>
to..
<pre>/bin/umount -a -r -t noramfs,notmpfs,nosysfs,noproc,cifs</pre>
