Public bug reported:
The LIO interfaces is inherently tied to the kernel.
That makes the service fail on e.g. a container install:
See "systemctl status rtslib-fb-targetctl.service" and "journalctl -xe" for
details.
root@f:~# systemctl status rtslib-fb-targetctl.service

It is ok that this doesn't work in a container, but it also breaks the package
installation status which should be avoided.
Until a more fine grained detection is developed that could be as easy as
adding:
ConditionVirtualization=!container
That would let the package install, but not start the service (knowing
it would fail).
