Even assigning uid=0,gid=0 to a regular user will not work, the
administrative command is submitted but will remain idle until you
remove it. Notice that there is no sudo installed by default on Debian.
Second option that I can think of: run slurm alongside HTCondor, just
give it 1 core only for running administrative tasks, the rest of cores
assigned to HTCondor Slots.
