Yes.

No. The machine has four PATA disks and only two PATA channels which means
that I cannot avoid sharing. I arranged the disks as they are now (raid0
on wd0 and wd1, raid1 on wd2 and wd3) to avoid performance hits on raid0
when raid1 (which e.g. contains my NetBSD source trees) is very busy.

	Kind regards
