This started off as a migration. It went down a rabbit hole of incorrect and undeclared dependencies. I’m going to post this as documentation for the required ports update.

There. Be gone. You don’t need the rest of this article. Thanks. Background As pointed out, …
This is not the first time this has happened. It last happened about a month ago. Tonight it happened for a different reason. This time it wasn’t the size of the mbox (I’m not using mbox on this server). This time it’s the size of the log. $ ls -lha ~/.mailfilter.log* -rw-r–r– 1 dan dan …

I first mentioned this idea yesterday. This morning I started implementing it. UPDATE: this strategy is mentioned in Scenic BGP Route | TechSNAP 137 at about 0:47:30. I back up my mail.
