All my Manjaro versions run so well that I have time to play around a bit.
Are there more elegant methods than
$ sed s/"Arming ConditionNeedsUpdate..."/"No errors."/g /usr/share/libalpm/hooks/systemd-update.hook > ~/a.hook | sudo mv a.hook /usr/share/libalpm/hooks/systemd-update.hook
Or more powerful in "autostart" , if Description in file is= Arming ConditionNeedsUpdate... then ...
I am open for all messages
