[sles-beta] Help, getting an autoyast build for "multi-user" target

[Darren Thompson]

Team

I have been doing some testing on getting a "default graphical build"
SLES12B8 server to become a "multi-user" server.

It's harder than you would think, mainly due to the way
display-server.service seems to be erroneously activated, even on
multi-user target boots.

I have found this process works:
1. Login to graphical console as root user.
2. run a "terminal" session (the yast service manager process is currently
broken, it would be Bets/easier to just run that).
3. cd /etc/systemd/system
4. rm default.target
5. ln -s /usr/lib/systemd/system/multi-user.target default.target
6. cd /usr/lib/systemd/user
7. rm default.target
8. ln -s /usr/lib/systemd/system/multi-user.target default.target
9. cd /usr/lib/systemd/system
10. rm default.target
11. ln -s /usr/lib/systemd/system/multi-user.target default.target
**** I have no idea why default.target is in these three locations, I would
expect 2 of them are redundant but am not familiar enough with systemd to
guess which ****

This will "tell" systemd that you want to run in "multi-user" mode (e.g.
the old init 3 level, without a X-server/GUI).

The problem is that the display-server.service still seems to be run on
boot (it mast be hard coded in somewhere) and I have not found a "working"
way of stopping it ('systemstl disable display-server' does not help).

What I have had to do is the following, which permanently stops the
display-server from starting.
12. systemctl mask display-server
*** reboot ***
13. shutdown -r now
(you can achieve the same result by typing: 'init 3') if you prefer not to
reboot.

I hope this is found to be helpful.
