Title: systemd-coredump user is created by something other than its derived systemd packages Status in systemd package in Ubuntu: New Bug description: systemd-coredump binary package is instructed as follows: #debian/systemd-coredump.postinst: adduser --quiet --system --group --no-create-home --home /run/systemd \ --gecos "systemd Core Dumper" systemd-coredump But one doesn't need this package to be installed to have the systemd- coredump user created. This was taken from a focal 20.04.2 fresh installation (Right after a vanilla installation): # cat /etc/passwd: ... systemd-coredump:x:999:999:systemd Core Dumper:/:/usr/sbin/nologin ... # dpkg -l | grep -i systemd ii dbus-user-session 1.12.16-2ubuntu2.1 amd64 simple interprocess messaging system (systemd --user integration) ii libnss-systemd:amd64 245.4-4ubuntu3.4 amd64 nss module providing dynamic user and group name resolution ii libpam-systemd:amd64 245.4-4ubuntu3.4 amd64 system and service manager - PAM module ii libsystemd0:amd64 245.4-4ubuntu3.4 amd64 systemd utility library ii networkd-dispatcher 2.0.1-1 all Dispatcher service for systemd-networkd connection status changes ii python3-systemd 234-3build2 amd64 Python 3 bindings for systemd ii systemd 245.4-4ubuntu3.4 amd64 system and service manager ii systemd-sysv 245.4-4ubuntu3.4 amd64 system and service manager - SysV links ii systemd-timesyncd 245.4-4ubuntu3.4 amd64 minimalistic service to synchronize local time with NTP servers # /var/log/syslog syslog:Feb 17 15:31:56 test systemd-sysusers[402]: Creating group systemd-coredump with gid 999. syslog:Feb 17 15:31:56 test systemd-sysusers[402]: Creating user systemd-coredump (systemd Core Dumper) with uid 999 and gid 999. Additionnally, you may notice the home directory during the user creation at installation sets it to "/" as opposed to "/run/systemd" directive in the appropriate postint. It is contradictory. * Why systemd-coredump user is created at installation time and/or without 'systemd-coredump' package installed ? * Why this early creation set the home directory to "/" ?
