Location of Application Unit Configuration Files

To configure the proper startup order of services, modify the unit configuration file for applications that require CTE to be running. You must also modify the secfs-fs-barrier.service file. The location of these files varies between Linux distributions as described in the following table.

Distribution	Location of systemd unit configuration files
RHEL 7 RHEL 8 SLES 12 SLES 15	`/usr/lib/systemd/system/<application_name>.service`
Ubuntu 16.04 Ubuntu 18.04	`/lib/systemd/system/<application_name>.service`
