** Description changed: + [Impact] + ======== + The LIO interfaces is inherently tied to the kernel.

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).
