I should write up a wiki page, but here is the details:
1. Add a file like: %{name}-tmpfiles.conf to the SOURCES tree containing:
D /run/my-package 0710 my-user my-group -
(this will create a folder call /run/my-package owned by
my-user:my-group in /run. You should likely use /run or /run/lock
directly rather than /var/run or /var/lock which are just symlinks to that).
You can also create files, links, named pipes etc. too. See "man
tmpfiles.d" for full syntax.
2. Add the source to the SPEC:
SourceN: %{name}-tmpfiles.conf
3. Install the tmpfile snippet:
# create tmpfiles directory
install -d -m0755 %{buildroot}%{_prefix}/lib/tmpfiles.d
install -m0644 %{SOURCEN}
%{buildroot}%{_prefix}/lib/tmpfiles.d/%{name}.conf
Make sure it's included in the %files section too:
%{_prefix}/lib/tmpfiles.d/*.conf
4. Add Requires:
Requires(post): systemd
5. Add/add to %post:
systemd-tmpfiles --create %{name}.conf
(note, passing in the file basename here is very important! Don't just
run "systemd-tmpfiles --create" as it has unexpected consequences!)
That's about it.
We could go around %ghosting the files created, but to be perfectly
honest, I don't think it's worth the effort. Files in /run should be
considered generally volatile and they should all be pretty self
explanatory generally IMO.
