Edit: Please see https://bugs.archlinux.org/task/40657, looks like there is a problem.

As I see this changes was made to /usr/lib/tmpfiles.d/systemd.conf in above lines - before was root root user (not systemd-network)
I don't have such user and that why my systemd-tmpfiles-setup.service not started.
Here the link to diff 0001-tmpfiles-systemd.conf-fix-ownership-of-network-direc.patch
Temporary back this three lines (24,25,26) ownership to 'root' user in /usr/lib/tmpfiles.d/systemd.conf
Is this bug or future?
