Be careful; systemd-tmpfiles has been in the news recently,
(see https://www.theregister.com/2024/06/20/systemd_2561_data_wipe_fix/ )
because it can delete your home directory.

Specifically, with respect to systemd v256, The Register warns:
  "If you invoke the systemd-tmpfiles --purge command without specifying
   that very important config file which tells it which files to handle,
   version 256 will merrily purge your entire home directory."

Apparently, systemd v256.1 makes some acknowledgement of this behaviour by
documenting it in the systemd help files.

Stay safe out there.
