Description Umut Tezduyar 2013-07-15 13:20:59 UTC 
There is no easy polling way to determine if system has booted up or not. 

while (systemctl is-active default.target == false)
   print "Still booting.."

systemctl list-jobs can be used to figure out if there are jobs left or not but the output of systemctl list-jobs is for humans. One thing could be printing out the number of ongoing jobs with "--quit" option..

ex: systemctl --quit list-jobs; echo $? > 0

Note: Yes, I am aware of the Manager interface's dbus signal sent out when boot up is completed.

We have a global system state now which "systemctl status" without parameters shows now.

You can also dump it like this:

systemctl show -p SystemState

If it is shown as "running" then the system is fully started up. This should cover what is necessary.

A well, I also added a high-level "systemctl is-system-running" command for this now to git.
