FreeBSD, OpenBSD and NetBSD are behind Linux.

Look, I dislike permissive licenses too, but you need a source to back this claim up.

Right now, each BSD does something special, that Linux (distro’s) can’t trivially replace, even if the usecase is more niche. NetBSD Dev’s make efforts to get it running on many devices as they can. OpenBSD (and it’s subprojects) are highly secure, moreso than Linux. Who do you think makes our beloved OpenSSH? OpenSSH noted for having very few vulnerabilities over it’s two decade long existence, and OpenBSD itself is similar, which is insane because there are products with multiple bad vulnerabilities every year (Linux being one of them…). This is due to a highly security minded architecture - one that Linux lacks.

FreeBSD is like Linux before systemd. I like systemd, but systemd is really trying to be kubernetes on a single node. I like systemd because I like kubernetes, but I understand why someone wouldn’t like it, and I question if “single node k8s” is the best architecture for a single server or personal desktop. The ports system results in freebsd packaging many server services that aren’t packaged on Linux. Being able to manage those through the system package manager, and the conviniences that provides, is nice.

Different, and not popular don’t mean bad.

This is technically yaml I think, a list (with one entry) of lists that contains mostly single items but also one other list. You should be able to parse this with a yaml parser like pythons built in one.

Note that yaml is picky abiut the syntax though, so it wouldn’t be able to handle deviations.
