Can a filesystem be larger than its base partition?

[Chris Rende]

[ Nixdorf Targon M35/50 TOS 3.2 - Pyramid 9810 OSx 4.0 - MP14 disks]

The System V Release 2 kernel allowed a file system to be built (MKFS'ed)
on a slice/partition which was larger than the slice/partition.
(I.e., file systems began on slice/partition boundaries but could
include other slices/partitions).

(Boy - this is hard to put into words).

On the Pyramid (BSD), Can a file system cross partition boundaries?

Can I MKFS a file system that uses all the disk space from pdisk00a,
pdisk00b, and pdisk00c on /dev/iop/pdisk00a?

Or, is /dev/iop/pdisk00o the only way to combine pdisk00[abc]? (o=a+b+c)
