ubuntu@test-f:~$ loginctl list-sessions
No sessions.
[regression potential]
any regression would likely occur during a systemd-logind restart, likely causing a loss of current login sessions.
[scope]
this is needed in f and earlier
this is fixed upstream by commit ac4e03d45bcf4ad2e570cabdb218e9bac003cc80 which is included in v246, so this is fixed in h and later already. |

in b, the function used to parse the /run/systemd/users/* files allows either usernames or uids, so this bug does not exist there |
