systemd

Am I running systemd or good old init?

To determine whether or not you're using old school, System V init or systemd (or a mix!), do the following:

$cat/proc/1/comm
systemd
$ls-l/sbin/init
lrwxrwxrwx1rootroot20May2608:07/sbin/init->/lib/systemd/systemd

Here, the system is using systemd.

If System V was in use, "init" would be printed in the first command and the latter command would show no symlink to systemd.

List all systemd available services

$ systemctl list-unit-files

You can grep for enabled and running to narrow down your search.
