delay.  Sickness
and offline family vacation jumped in between, next replies will come faster!

Running lxc-copy for unprivileged containers fails for us, see error
messages I (a few seconds ago) pasted into the bug description.  A
colleage pointed me to

https://ubuntu.com/blog/ubuntu-23-10-restricted-unprivileged-user-
namespaces

and this matches our view on the actual situation.  Fixing the profile
file for lxc-copy helps *really* when attempting to copy containers
unprivileged here.

But I have no clue, why the other unconfined profiles do not have such
an impact.


> b) d/changelog

thanks for the hints, changelog entry is fixed.


> c) Bug description

again: thanks for hints and links.  I added and filled-on the SRU bug
description by best knowledge.  Do you think this is complete enough?
Or do you see more open/missing points?


Thanks a lot and kind regards,
Nicolas
