I'm trying to build a rpm package that enable a systemd service the proper way.

In my rpm spec file, I added:

```
%{?systemd_requires}
BuildRequires: systemd

...

%postun
%systemd_postun yeah.service

```

My rpm copy in /usr/lib/systemd/system/ the yeah.service file.

But after package installation, the service is still disable:

```
root@ansible-1:1:~# systemctl status yeah
Unit yeah.service could not be found.
root@ansible-1:1:~# rpm -Uvh /home/intersec/delivery/yeah.rpm
Preparing...                          ################################# [100%]
Updating / installing...
   1:yeah################################# [100%]
root@ansible-1:1:~# systemctl status yeah
● yeah.service - Yeah
   Loaded: loaded (/usr/lib/systemd/system/yeah.service; disabled; vendor preset: disabled)
   Active: inactive (dead)

```

What's wrong?
