During debugging a startup issue I started using systemd debug shell. The shell would be a lot more useful if systemd wouldn’t write its status about units to console, because the output disturbs the output of commands in the debug shell.
Especially the update of the time while waiting for a unit to finish (which is written every second) I found really annoying.
I searched for a way to disable this output or even better have it only printed every x seconds, but didn’t find anything.
Also scrolling back in console while startup is impossible, because with every update it jumps back to the end.
