Actually in my setting the UML has it's own partition directly (/dev/hda3).=
 As far as I know, this is the fastest setup possible with regards to disk=
 access, as opposed to using COW or other rootfs systems.

>Another thing that really hurts anything that's writing to disk is the

I know, and that's why I don't use synchronous write. In my particular case=
, speed matters a lot.=20

The groupware server installation which I plan to run inside UML will only=
 store archive e-mail, which doesn't change very often so taking daily back=
ups is safe enough. Also, the groupware software itself has some very good=
 database recovery tools, ensuring that data will be recovered even after=
 very nasty crashes.

Best regards,
Sebastian
