** Description changed:
+ [Impact]
+ ========

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
+ [Test Plan]
+ ===========
- That would let the package install, but not start the service (knowing
- it would fail).
+ To reproduce this bug, simply do the following:
+
+ $ lxc launch ubuntu-daily:groovy python-rtslib-fb-lp1865037-groovy
+
+ $ lxc shell python-rtslib-fb-lp1865037-groovy
+
+ # apt update && apt upgrade
+
+ # reboot
+
+ # apt install python3-rtslib-fb
+
+ ...and this should fail to install.
+
+ To make sure that this bug is indeed fixed, install the patched version
+ of this package and that should install fine.
+
+
+ [Where problems could occur]
+ ============================
+
+
+ This is a workaround since there doesn't seem to be a in-container use case.
But in case there is one, then that'd fail to work, so we might better find a
better solution for this in the long term.
+
+ The disccusion has been initiated upstream (cf: https://github.com/open-
+ iscsi/rtslib-fb/issues/157) and probably we'll wait for upstream to
+ state some in-container use case(s).
