Package: systemd Version: 241-1 Severity: normal Hi,
The description of the systemd package states that installing it will not switch the init system, unfortunately that's what happens, unless systemd is installed with --no-install-recommends. It looks like a recommended dependency (libpam-systemd?) triggers the removal of sysvinit-core. I haven't been able to track exactly why it happens in testing with the version 241-1. With the version 241-2 in sid I guess the removal of systemd-shim from the alternative dependencies of libpam-systemd [1] last week doesn't help. root@sysvinit:~# ps aux USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.0 7900 1980 pts/1 Ss+ 09:29 0:00 init [2] root 884 0.0 0.1 156188 2412 ?
