SELinux preventing service from starting when symlink points to systemd unit file in NFS

Issue

• User is using NFS for storing application binaries and files.

• A symlink /etc/systemd/system/customsystemd.service points to a systemd unit file in NFS.

• Checking if service is enabled fails:

  [root@rhel9:~]# systemctl is-enabled customsystemd.service
  Failed to get unit file state for customsystemd.service: Access denied
  

• Checking service status fails:

  [root@rhel9:~]# systemctl status customsystemd.service
  Unit customsystemd.service could not be found.
  

• Starting the service fails:

  [root@rhel9:~]# systemctl start customsystemd.service
  Failed to start customsystemd.service: Unit customsystemd.service not found.
