Still trying to get the patched 8.1-STABLE built as a release DVD so I
can try it out on my MacBookPro, but...
... on the build box, I'm getting problems accessing ZFS snapshots using
RELENG_8 from Sat 20th with the pat-stable.diff patches:

Possibly coincidental -- I'm building world without the patches now, but
I won't know the result until I get back from work this evening.
