Another option is to do this in your soruces btw:
```c
(void) kill(1, SIGRTMIN+21);
```
Sending SIGRTMIN+21 to PID 1 will disable the status output
explicitly. If you are sure you don't want it you can just do that, in
one line.
Plymouth also sends that signal, hence make sure you don't run into
races with that.
That won't work, the primary use-case for the offline-updates
status display is a user pressing ESC while plymouth is showing this:
https://fedorapeople.org/~jwrdegoede/flickerfree-videos/installing.png
So that the user can see details if he/she wants that. In this case
plymouth will send SIGRTMIN+22 when switching back to text-mode to
have systemd resume its status messages, so having pk-offline-update send
SIGRTMIN+21 when it starts will not help.
Could the plymouth theme somehow suppress the sending of SIGRTMIN+22?
e.g. in the case of the offline updates it's presumably integrating with
the pk-offline-update to get progress reports anyway, so it knows the
context in which it's run. I could simply suppress the sending of
SIGRTMIN+22 and leave just the pk-offline-update messages?
Obviously would need a tweak to plymouth, but perhaps it's not too
crazy? Just a thought.
That only fixes the case when plymouth is running, but we really cannot
assume that that is always the case.
Regards,
Hans
