+
+
+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.
+
