Because the sage.math hardware was physically broken when I did the
upgrade on the temporary replacement for sage.math, so when we swapped
back we got back the non-upgraded sage install.
I'm fixing it right now.

Yes.  We have very large Sun Fire X4540 running OpenSolaris with zfs,
and for reasons still unknown, the performance is horrible.   Using a
random $300 USB disk plugged into a laptop and served over NFS would
give better performance (I'm not exagerrating).   Obviously we wish to
remedy this.

Note that zfs does have some cool features, e.g., look at
/home/.zfs/snapshot to see snapshots into the past of the filesystem
state.
