Thread: Fix for pgbackrest systemd service file

Fix for pgbackrest systemd service file

From

Good afternoon,

I was talking with David Steele and pointed out errors I saw in the pgbackrest service file when doing some early TLS file. It looks like the errors stem from line 15 where the kill command doesn't have the absolute path, and should be /bin/kill. I confirmed the errors go away when I specify the full path to the kill binary.

I've given David this info and he is updating their documentation to reflect the change also.

Before:

$ sudo systemctl status pgbackrest
● pgbackrest.service - pgBackRest Server
   Loaded: loaded (/lib/systemd/system/pgbackrest.service; disabled; vendor preset: enabled)
   Active: inactive (dead)

Jul 19 16:37:44 postgres-history0-az-eastus2 systemd[1]: /lib/systemd/system/pgbackrest.service:15: Executable path is not absolute: kill -HUP $MAINPID

After:

$ sudo systemctl status pgbackrest
● pgbackrest.service - pgBackRest Server
   Loaded: loaded (/lib/systemd/system/pgbackrest.service; disabled; vendor preset: enabled)
   Active: inactive (dead)

Just noticed I pasted the wrong clip here for the "Before" example. This should show that there's a failure to load with a formatting error specified. I'll try to get the actual text later, I'm not at my workstation at the moment.

Thanks for reporting this issue. The fix will be included in the next 
package update.
