Description Scott Poore 2018-12-12 23:00:39 UTC

Description of problem:

I ran into an issue when setting up systemd-journal-upload to "send" journal log entries to a remote host.  It appears that 

[root@vm2 CA]# grep User= /lib/systemd/system/systemd-journal-upload.service
User=systemd-journal-upload
DynamicUser=yes

[root@vm2 CA]# id systemd-journal-upload
id: ‘systemd-journal-upload’: no such user


Version-Release number of selected component (if applicable):
systemd-journal-remote-239-8.el8.x86_64

How reproducible:
always

Steps to Reproduce:
1.  dnf install systemd-journal-remote
2.  id systemd-journal-upload

Actual results:
no user created.

Expected results:
since the service sets a user, I would expect the rpm to create it during install.

DynamicUser= creates the user dynamically at runtime and frees the allocation when the service finishes. The user is not added to /etc/passwd or similar and "id" command won't show it. For more information, see man systemd.exec(5), section CREDENTIALS.
