Enabling of mysql on Fedora20 doesn't work after latest operating system update

[Sergey Gotliv]

After latest update of Fedora installation of mysql with Trove guestagent is broken. It looks like systemd stopped supporting absolute path to the unit file.

For exmaple:

systemctl enable /usr/lib/systemd/system/mariadb.service

returns "Failed to issue method call: Invalid argument"

while "systemctl enable mariadb.service" works.

According to the systemctl man page absolute path should be supported:

"For Unit File Commands the NAME represents full name of the unit file, or absolute path to the unit file.

           systemctl start /path/to/foo.service
"

But till systemd will fix the issue, I have to fix it in Trove to make it possible to install mysql on Fedora guest.

    Use unit file to enable systemd service

    Although systemd's systemctl should support an absolute path for unit
    file commands like for example 'enable', it seems like after latest
    update of my Fedora 20 environment, the following doesn't work anymore,
    see:

    https://bugzilla.redhat.com/show_bug.cgi?id=1174370

    Following command fails with absolute path:

    systemctl enable /usr/lib/systemd/system/mariadb.service

    But works when replacing absolute path by unit file name only:

    systemctl enable mariadb.service
