Trying to understand the usage for “Services Manager”, which appears to have replaced the old “System Services” module. Documentation (https://activedoc.opensuse.org/book/opensuse-reference/chapter-8-the-systemd-daemon) for systemd still refers exclusively to the old module.
In the upper left is a dropdown labelled Default System Target. Its values are:
Ctrl-Alt-Del
Graphical Interface
halt
kexec
poweroff
reboot
remote file systems
Rescue mode
runlevel0
runlevel1
runlevel6
“Ctrl-Alt-Del” appears to be the default. I have a vague idea of how most of these terms might map to runlevels, but clicking on the “Help” button gets me a blank dialog box with a close button. It’s not at all clear to me what interaction there is between setting Default System Target and toggling the Start/Stop or Enable/Disable buttons for each service. Surely this stuff is documented somewhere…
In Leap 42.1, I am seeing options:
Graphical Interface
Emergency Mode
Switch Root
Initrd Default Target
Multi-User System
Rescue Mode
The normal choice is “Graphical Interface” for most users. But “Multi-User System” would be appropriate if you only wanted the usual command line. The others all seem to be special purpose choices.
As for stop/start and enable/disable – those are somewhat independing of the Default System Target. “Start/Stop” is what to do about the service for this current session. And “Enable/Disable” is what to do on future boots.
Thanks for the response. I just noticed I never indicated my OpenSUSE version (13.1).
I did find this (https://www.suse.com/documentation/sles-12/book_sle_admin/data/sec_boot_runlevel_edit.html), with a description of Services Manager that matches yours.
From your description, it sounds like my install of Services Manager is at least somewhat messed up. As it turns out, I don’t need to make any changes at the moment anyway, so I think I’ll just put that aside for another day.
