Nope.. obviously trying to do things the hard way :p)
cd /tmp ; cat /dev/zero > tmpzero ; sync ; rm tmpzero
Does the job nicely from within the VM.
Thanks for all the replys, I obviously have too much time on my hands.

On another UML related note, installing the skas patch on the host 
speeds up the uml session something wicked..

This machine is becoming VM city.. I use uml with debian woody for 
evolution, BasiliskII for M68k Mac emulation, win4lin to run win95 so I 
can run the freeware ida-pro and Borland Delphi, Dosemu running some 
control software and Crossover Office for Word 97.
Plus OpenOffice and the Gimp..
BasiliskII is the only VM that gets shut down when it's not being used 
as it hogs 100% cpu all the time. The rest are up whenever the machine 
is on.

Plus it never gets shut down, I just suspend it with swsusp.
