To the mysql init script, I added: # REQUIRE: dhclient And to the dhclient init script I added: # REQUIRE: NETWORKING In addition to changing DHCP to SYNCDHCP in rc.conf, mysql now starts up on boot. I would think the dhclient change should be required in the default setup since NETWORKING should be up before attempting to grab a dhcp IP, or am I misunderstanding here? Either way, the above seems to have solved my problem. Thanks! Rob Matthew Seaman wrote: > Rob wrote: >> Since I upgraded to FreBSD 8.0, I'm noticing that mysql isn't starting >> on boot anymore.
