Re: [HTCondor-users] Running a script on job start as root

[Thomas Hartmann <thomas.hartmann@xxxxxxx>]

Hi Max,

I had also been thinking about something in that direction and one idea 
was if one could use a path unit/inotifies. I.e., to set up outside of 
condor a path template unit for all possible slots in the corresponding 
job slot cgroup. And when a new job is started and the cgroup path gets 
created or updated, trigger a script for updating the controller magic.
Unfortunately, I have not get very far and put it onto my project heap 
until having more time.

Cheers,
  Thomas

We donât want to let the user run the adjustment program, so USER_JOB_WRAPPER  with sudo/setuid and friends is out of the question, too.
