Tmpfiles
systemd.tmpfiles.packages
List of packages containing {command}systemd-tmpfiles rules.
All files ending in .conf found in
{file}«pkg»/lib/tmpfiles.d
will be included.
If this folder does not exist or does not contain any files an error will be returned instead.
If a {file}lib output is available, rules are searched there and only there.
If there is no {file}lib output it will fall back to {file}out
and if that does not exist either, the default output will be used.
