Adding Applications to the secfs-fs-barrier.service File

After editing the systemd unit configuration file for each dependent application, you must also add each application to the secfs-fs-barrier.service file that is installed as part of CTE. The secfs-fs-barrier.service file ensures that CTE starts before dependent applications during boot and CTE stops before dependent applications when the system is shut down.

1. As a root user, open the secfs-fs-barrier.service file in a text editor such as vi.

   For example, the secfs-fs-barrier.service file is located in /usr/lib/systemd/system/secfs-fs-barrier.service.

2. Add saslauthd.service along with the names of the unit configuration files that you edited in the last section to the end of the “Before=” clause.

   For example, the secfs-fs-barrier.service file might contain the following before editing:

   Before=postgresql.service httpd.service mongodb.service mongod.service mysqld.service mariadb.service nails.service

   To add an entry for saslauthd.service and two custom application services called example1.service and example2.service, you would edit the Before= line to look like this:

   Before=postgresql.service httpd.service mongodb.service mongod.service mysqld.service mariadb.service nails.service saslauthd.service example1.service example2.service

3. Save and close the secfs-fs-barrier.service file.

In the future, CTE will start before each application listed in the Before= line and those applications will stop before CTE stops.
