In it's current version (systemd-229-4ubuntu21.9) it seems to be made worse.

After a recent reboot I found most of my services to be in a failed state. The reason for that, I guess, are these log entries: Nov 17 04:47:42 h2118376 systemd-tmpfiles[165]: fchownat() of /run/elasticsearch failed: Invalid argument Nov 17 04:47:42 h2118376 systemd-tmpfiles[165]: fchownat() of /run/kopano failed: Invalid argument Nov 17 04:47:42 h2118376 systemd-tmpfiles[165]: fchownat() of /run/kopano failed: Invalid argument Nov 17 04:47:42 h2118376 systemd-tmpfiles[165]: fchownat() of /run/php failed: Invalid argument Nov 17 04:47:42 h2118376 systemd-tmpfiles[165]: fchownat() of /run/postgresql failed: Invalid argument Nov 17 04:47:42 h2118376 systemd-tmpfiles[165]: fchownat() of /run/redis failed: Invalid argument Nov 17 04:47:42 h2118376 systemd-tmpfiles[165]: fchownat() of /run/screen failed: Invalid argument Nov 17 04:47:42 h2118376 systemd-tmpfiles[165]: fchownat() of /run/utmp failed: Invalid argument Nov 17 04:47:42 h2118376 systemd-tmpfiles[165]: fchownat() of /run/systemd/netif failed: Invalid argument Nov 17 04:47:42 h2118376 systemd-tmpfiles[165]: fchownat() of /run/systemd/netif/links failed: Invalid argument Nov 17 04:47:42 h2118376 systemd-tmpfiles[165]: fchownat() of /run/systemd/netif/leases failed: Invalid argument Nov 17 04:47:42 h2118376 systemd-tmpfiles[165]: fchownat() of /run/log/journal failed: Invalid argument Nov 17 04:47:42 h2118376 systemd-tmpfiles[165]: fchownat() of /run/log/journal/bbad3a438f4b4fb49e5d0700bd5981e8 failed: Invalid argument Nov 17 04:47:42 h2118376 systemd-tmpfiles[165]: fchownat() of /run/log/journal/bbad3a438f4b4fb49e5d0700bd5981e8/system.journal failed: Invalid argument To verify I tried this: /usr/lib/tmpfiles.d# SYSTEMD_LOG_LEVEL=debug systemd-tmpfiles --create elasticsearch.conf Reading config file "elasticsearch.conf".

My suspicion is, this is related to an upgrade of systemd to 229-4ubuntu21.8. At this point I don't know what to do. I'm also confused about the version I have installed, which I thought is systemd-229. Howver, I looked at https://github.com/systemd/systemd/blob/v229/src/tmpfiles/tmpfiles.c and found that fchownat() is only used from version 238+: Tag v237 (and earlier, including 229): /.../ if (chown(fn, i->uid_set ? i->uid : UID_INVALID, i->gid_set ? i->gid : GID_INVALID) < 0) return log_error_errno(errno, "chown(%s) failed: %m", path); } /.../ Tag v238 /.../ if (fchownat(fd, "", i->uid_set ? i->uid : UID_INVALID, i->gid_set ? i->gid : GID_INVALID, AT_EMPTY_PATH) < 0) return log_error_errno(errno, "fchownat() of %s failed: %m", path); /.../ Any help fixing this problem would be highly appreciated.
