Bug#929462: systemd-journal-remote: systemd-journal-upload user missing

[Paul Emmerich]

Package: systemd-journal-remote
Version: 241-3
Severity: grave
Justification: renders package unusable
Tags: newcomer

Dear Maintainer,

we are maintaining a Debian live image that uses systemd-journal-remote to
send log files to a log collector. The systemd-journal-upload unit fails
to start on buster:

May 22 07:23:34 ceph06 systemd[1]: Starting Journal Remote Upload Service...
May 22 07:23:34 ceph06 systemd[40869]: systemd-journal-upload.service: Failed to determine user credentials: No such process
May 22 07:23:34 ceph06 systemd[40869]: systemd-journal-upload.service: Failed at step USER spawning /usr/local/bin/update-journal-configuration.sh: No such process

It tries to run as user systemd-journal-upload which seems to be missing.

Fix is to add the user, mkdir /var/lib/systemd/journal-upload and chown
the dir to the new user.

It's entirely possible that we are doing something wrong when creating the
live image, but it's just a standard debootstrap followed by apt-get install
systemd-journal-upload in a chroot.
Virtually identical setups works for Stretch.
