While cleaning a storage room, our staff found this tape containing #UNIX v4 from Bell Labs, circa 1973

Apparently no other complete copies are known to exist: https://gunkies.org/wiki/UNIX_Fourth_Edition

We have arranged to deliver it to the Computer History Museum

NEW VIDEO: I Left Linus Media Group - What do I do now?

Y’all, I love my enormous dog. I love hugging him. I love that he cuddles like a tiny cat. I love waking up and seeing him curled up asleep next to my bed. I love that he’s still getting even bigger

Beware of systemd-tmpfiles --purge in systemd 256 -- it will delete a lot more than just temporary files, e.g. your /home dir! And apparently that is by design! (Wildly unexpected for me, as it goes beyond what the man pages says the tool does - manipulate volatile and temporary files and directories).

See the man page, there is a description of the new option:
https://manpages.debian.org/unstable/systemd-standalone-tmpfiles/systemd-tmpfiles.8.en.html

1) Use --dry-run to see what would get deleted.
2) There is a /usr/lib/tmpfiles.d dir where default tempfile definitions are stored, including for /home.
3) There is an issue to rectify this - https://github.com/systemd/systemd/issues/33349 - at least on the docs side, but the discussion goes beyond that.
EDIT 4) the --purge was apparently meant to aid with package deconfiguration and stuff like that, and was meant to be used with a configuration file -- the commits/PRs indicate that systemd shall not allow the use of that option without specifying a config file, in next versions.
