The binary is setuid to root so that should not be a problem.

I am seeing the same freezes. I am running NT4 on a virtual drive.
From time to time, the NT in vmware freezes. The IDE light on the vmware
screen is off, yet there is a tremendous amount of disk activity
going on (as seen from iostat or systat -vmstat). I am seeing
100 transaction per second. There is no paging or swapping going on
(as seen by FreeBSD), so I can only assume that something is happening
inside the virtual drive. But it is NOT NT doing that because
otherwise we'd see the IDE pseudo led on...

Are there any people that run NT in vmware on a Linux box listening
here? If so: do the see the same disk activity?
