I am already in love with it, since I plan to use it as a HA-firewall using carp and pfsync. Problem here is just that it looks as if I had to reinstall it all year ...
If that's the case, then you just take one down, upgrade it, bring it back online, take the other down, upgrade it, bring it back online. I fail to see the issue here. 'nuff said.
