… you can easily turn it off via the --background= switch). It also inserts a red dot (unicode ftw) in the window title while you operate with privileges, and drops it afterwards.
And since it's just systemd-run called under a different name it supports the --property= switch that systemd-run supports, i.e. it allows you to set arbitrary service settings for the invoked privileged command/session if you like.
Anyway, that's all for now. Enjoy "run0"!
@pid_eins When you say "while you are operating with elevated privileges", do you mean you can use run0 to create a root shell to work in, or do you just mean while the current programm I started as run0 ist running?
