Enjoy it while it lasts.
We've got a number of upgrades going on, which means that since subtle changes are occurring, that we have to perform complete tests on these systems (i.e. not the hardware, but our software configurations.)
This week I'm building a tiny lab of six machines to test a roll out of OpenBSD 4.7 on one of our redundant (carp) firewalls. Since rule changes are really a good excuse to revisit how you've written your previous version, then it is a good time do a thorough review (test in and out activity etc.)
