All three schedulers (Torque, slurm, condor) will be configured to start via systemd. The file pbs_mom, slurm, and condor in /etc/sysconfig will be set such that all of these schedulers will fail to start on boot.
/etc/sysconfig/pbs_mom: PBS_ARGS="-h"
/etc/sysconfig/slurm: SLURMD_OPTIONS="-h"
/etc/sysconfig/condor: CONDOR_CONFIG=/nosuchfile
If any of these schedulers are wanted to start on boot, the appropriate /etc/sysconfig file (pbs_mom, slurm, condor) will be altered via a snapshot.
/etc/sysconfig/pbs_mom: PBS_ARGS="-h"
/etc/sysconfig/slurm: SLURMD_OPTIONS="-h"
/etc/sysconfig/condor: CONDOR_CONFIG=/etc/condor/condor_config
