That must be it then, the el7_2.7 version must be having some trouble with 
it. I'll plan to apply the patches and reboot at some point in the near 
future. (Treating Linux like Windows - already not a fan of systemd.)

Even in spite of the error it's showing, it appears that it's working 
based on lscgroup of a job running on RHEL7 and it's showing the 
BASE_CGROUP = htcondor configuration I've set up:

blkio:/
blkio:/htcondor
blkio:/htcondor/condor_data_condor_execute_slot1_1@hostname

At first glance I thought it might be because the ControlGroup line 
specifies ControlGroup=/condor rather than /htcondor to match BASE_CGROUP, 
but it's complaining about the lvalue, so it's going to be an issue with 
the systemd version.

Klint, do you have BASE_CGROUP set to "condor?"
