Well the only reason it might not be is that it hasn't seen widespread testing, as far as I can tell it should all just work.

As far as I can tell, it should just work. To pick up the latest round of vinum fixes it might be best to run 5-STABLE (ie. RELENG_5) but it should not be necessary unless you run into difficulties. But the only way to know for sure if things work, is to test... --Stijn [1] for some reason I discovered a configuration problem earlier this week, but the other part of the mirror is holding up and it seems that I can reconstruct the broken part this weekend. If anything, it seems that a gvinum mirrored plex is robust. --=20 "Coca-Cola is solely responsible for ensuring that people - too stupid to k= now not to tip half-ton machines on themselves - are safe.
