[oe] systemd service not enabled when adding simple recipe to image

[Sandro Stiller]

Hello,
I have a problem enabling a simple systemd service:
If I install my package using the .ipk file, everything works fine
(systemd service ist enabled after install), but if I create an image
containing this package, the service is disabled.
It can be enabled by calling "systemctl enable <mytestscript.service>".
All files of the package are installed correctly (only the systemd
symlink is missing). I have other packages with working systemd, the
problem exists only in the simple case with a single shell script.

I use Angstrom v2015.06 / Yocto 1.8

Can anybody tell me what I'm doing wrong?

Thank you very much,

Sandro
