This reworks commit 20e1508e, for two reasons:
- Upstream D-Bus now does the same (although this isn’t yet reflected in the online version of the D-Bus Specification); see https://gitlab.freedesktop.org/dbus/dbus/-/merge_requests/209.
- It allows local-prefix (e.g. jhbuild) builds of GLib to build in a
custom prefix while still interacting with system services using the
system-wide
/rundirectory. To do so, pass-Druntime_dir=/runto meson configure.
As documented in the NEWS file in
https://gitlab.freedesktop.org/dbus/dbus/-/merge_requests/209, it’s only
valid to use /run – rather than /var/run – for D-Bus if the two
paths are interoperable. i.e. /var/run should be a symlink to /run,
and the D-Bus daemon should be configured to put its socket there.
This commit deliberately doesn’t introduce a special system_socket
configure option for specifying where the D-Bus system socket lives, as
that would only be useful for a distribution which sets runstatedir to
something other than /var/run or /run, which seems unlikely. We
could add such an option in future, though, if a distribution comes
forward with such a requirement.
See discussion on !3095 (comment 1605502).
