Is what populate-volatiles does truly equivalent? Does this directory
need to be owned by messagebus (which is a user created by dbus) iirc?
Cheers,

The dbus recipe writes /etc/default/volatiles/99_dbus.
For sysvinit case, this will cause populate-volatiles.sh to create
/var/run/dbus owned by messagebus:messagebus with 0755 permissions so it
is the same.
The systemd init doesn't use populate-volatiles.sh and it's created
implicitly so it is owned by root:root with 0755 permissions.
For distributions using sysvinit (e.g. Debian), /var/run/dbus is
typically owned by messagebus:messagebus. There is no dbus user/group in
/etc/passwd or /etc/group.
For distributions using systemd (e.g. Arch Linux and Fedora),
/var/run/dbus (actually /run/dbus) is typically owned by root:root.
There is no messagebus user/group in /etc/passwd or /etc/group, but
there is dbus.

Jonathan
