Brian DorseyI've started learning FreeBSD. Goal is to use it for self hosting and learn about ZFS & jails. So far, it feels both nostalgic and as if it came from an alternate future.

JdeBPYou wait until you learn that there's a handful of #Illumos-based operating systems still available.
In that alternate, the operating system has STREAMS and 'zones', uses the Service Access Facility (the Unix System 5 Release 4 replacement for Release 3 init+rc that almost everyone has since forgotten, that replaced in 1988 what people erroneously think of today as 'system v init') as part of its Solaris descendent the Service Management Facility, and also has ZFS and boot environments.
It, too, like the BSDs, has a different feel to the world of Linux-based operating systems.
