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.

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).
