I remember on SXCE running on my test Sun E420r server that ZFS (can't
remember if this was in the spec file or not??) would use **any** usable
or unpartitioned file system as swap. I maybe totally off-base with this
as I was too knew to investigate the issue and was still learning
Solaris at the time but all of a sudden a remote mounted external drive
would start getting zapped by I/O usage. Of course it couldn't be any
user as the only user for those machines was me and I wasn't doing
anything on either system.


That was quite a weird thing, but happened many years ago so my memory
is quite hazy on the specifics of the issue too....

I do recall running top to see swap usage at a few tens of gigs which
was quite funny, of course unmounting the drive dropped the swap back to
whatever got allocated by SXCE default.
