kgb-bot isn't configured to join #tor-admin
kgb-bot.service needed a restart, and when it came back up it joined #tor-www and #tor-bots, but not #tor-admin. I checked the config file, and it's just missing an entry for the #tor-admin channel.
What's more, it doesn't look like it's being configured with puppet. The puppet config has no channels or networks configured, and the kgb-bot config file doesn't include the # THIS FILE IS UNDER PUPPET CONTROL
warning.
I'm hesitant to "fix" either of those things without knowing if they're intentional.
