It's risk free. Only time I've ever used it was when I had a floppy
mounted, and wanted to force it to write a load of stuff to it before
unmounting. Though I suppose umount /mnt/floppy would have done the job
It's usually run as the "sync" user on older systems, I think, like SCO,
so maybe it *had* to be runnable by normal users...
The words of the unwary are apt to cause needless pain and bloody violence.
