custom job to be prioritised against system jobs - Take 2

[Luigi Capriotti]

Having found examples of wait-jobs I gave it a try but still no success.

My custom jobs are something like:

# myjob
start on (starting lightdm or starting ubiquity)
task

script
	# blablabla

end script


#Myjob-wait
start on (starting lightdm or starting ubiquity)
stop on (started myjob or stopped myjob)

instance $JOB
normal exit 2
task

script
     status myjob | grep -q "start/running" && exit 0
     start myjob || true
     while sleep 3600 ; do :; done
end script


but at runtime I can see that ubiquity runs while my job is still not 
completed.

This is the related part of the syslog:

Again, thanks in advance for any help.
