Description of problem:
SELinux is preventing systemd from 'watch' accesses on the directory /var.

*****  Plugin catchall_labels (83.8 confidence) suggests   *******************

If you want to allow systemd to have watch access on the var directory
Then you need to change the label on /var
Do
# semanage fcontext -a -t FILE_TYPE '/var'
where FILE_TYPE is one of the following: NetworkManager_unit_file_t, NetworkManager_var_run_t, abrt_unit_file_t, abrt_var_run_t, accountsd_unit_file_t, aiccu_var_run_t, ajaxterm_var_run_t,

Then execute:
restorecon -v '/var'


*****  Plugin catchall (17.1 confidence) suggests   **************************

If you believe that systemd should be allowed watch access on the var directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'systemd' --raw | audit2allow -M my-systemd
# semodule -X 300 -i my-systemd.pp
