I stand corrected, and I see I didn’t read the comment thoroughly enough either.

Colloquially as a non-pcb maker I would use and hear the term “mill” as short form millimeter so I assumed it was that.

so TIL :)

A millimeter i.e a thousands of a meter.

edit: I was wrong, confusingly enough it is a thousands of an inch

It’s not necessarily better, some things are a personal preference. Though some might be able to list some technical pros and cons.

Some things I appreciate are:

• base systems and packages are completely separate. Packages and their configuration goes in /usr/local/ No where else. (Thought they might write to /var/ )
• bsd init, not systemd. Feels more home to me as a late 90s slackware user.
• first class zfs support. Linux has caught up lately, especially now that there is a shared zfs codebase for both Linux and FreeBSD. When I switched to FreeBSD on my home server ~10 years ago that wasn’t the case.
