journalctl --vacuum-* --directory… does not remove anything in remote journal storage #2376
Description
I'm running systemd-journal-remote and let it write to the default location, /var/log/journal/remote. There are currently 589 files in that directory occupying ~17.6 GB:

I would very much like to use the various --vacuum-* options to journalctl but they don't do anything at all with those files:
[0 root@belgarath /var/log/journal/remote] journalctl --directory=/var/log/journal/remote --vacuum-size=1G
[0 root@belgarath /var/log/journal/remote] ls | wc -l
589

I can see journalctl accessing all those archived files if I strace it, so it does seem to work on the right directory at least:
[0 root@belgarath /var/log/journal/remote] strace -e trace=open journalctl --directory=/var/log/journal/remote --vacuum-size=1G |& tail

Is this supposed to work? Is the only way to actually remove entries from a remote journal storage the manual rm remote-belgarath@*.journal or something like that?
Thanks.
