This looks pretty close to what I'd like to see in place. Note that
%_tmpfilesdir is already set in macros.systemd as we ship it upstream.

My suggestion would be this however:

_tmpfiles_create() \
/usr/bin/systemd-tmpfiles --create %{1} >/dev/null 2>&1 || : \
%{nil} 

I thik that people should specify file names rather than package names
(just to keep this closer to the underlying command and to make the
multiple drop-in case less exotic, and since we require the suffixe for
the unit macros too) and ignore errors. Also, add an underscore since
our other macros use the same naming style.

Hmm, I'd like such an automatism, but I'd really prefer if we could come
up with some scheme to automatically determine all tmpfiles snippets in
the package and apply them all automatically. But I am not sure how that
could be done with current RPM.

In fact, I'd actually like to do the same for the %systemd_post macros,
and suchlike, where people tend to be pretty bad at always listing all
unit files correctly.

Anyway, does that RPM macro sound good to you? If so, let's add this to
macros.systemd and I'll ask our Fedora guys to add this to the
guidelines.
