I'm not entirely sure, if it's the missing ACL support or some other
missing feature in NFS (at least on an ext4 file system where acl and
user_xattr support has been disabled via tune2fs -o ^acl I do not get
such a failure).

It's probably best if you file this upstream at
https://github.com/systemd/systemd.
I don't really have the necessary setup to be able to reproduce this myself.

The command in question is
mkdir -p /var/log/journal
systemd-tmpfiles --create --prefix /var/log/journal

It's probably a good idea, if you run systemd-tmpfiles under strace and
attach the strace log to the upstream bug report.
