Bug 476818 – Systemd guide should explain people how to prevent tty1 clearing (like it's documented with agetty+openrc)

• Status: CONFIRMED
• Product: Gentoo Linux

[Description Pacho Ramos 2013-07-14 11:06:10 UTC]

I found it in:
https://wiki.archlinux.org/index.php/Disable_Clearing_of_Boot_Messages

And would incorporate it to our wiki if you don't disagree

Reproducible: Always

Added

Re-opening this. Telling people to modify that file directly is not a good idea.

floppym@naomi ~ % readlink /etc/systemd/system/getty.target.wants/[e-mail]
/usr/lib/systemd/system/getty@.service

Effectively, you are telling them to edit /usr/lib/systemd/system/getty@.service, which will get overwritten during their next systemd upgrade.

[Comment 3 Mike Gilbert 2013-07-20 23:48:33 UTC]

I have removed that small paragraph from the wiki.

A better solution is this, which overrides the getty@.serivce file.

floppym@naomi ~ % cat /etc/systemd/system/getty@.service 
.include /usr/lib/systemd/system/getty@.service
[Service]
TTYVTDisallocate=no

I'm not sure where to put that in the wiki article though. Maybe in the section about "custom" units?

Or maybe as a new subsection below "custom" but still inside "configuration" section

[Comment 5 Alexander Tsoy 2013-07-23 15:48:48 UTC]

Another solution:

$ cat /etc/systemd/system/[e-mail].d/noclear.conf 
[Service]
TTYVTDisallocate=no

Oh, I forgot about the foo.d option. I like this better.

I agree, only doubt about where to place it :(

Other option would be to install this file (commented), what do you think?

That is what opensuse people is doing
