Code review comment for ~ahasenack/ubuntu/+source/tomcat9:kinetic-tomcat9-logging-fix

Wow there are really a lot of combinations of different actions and their order to consider here.
AFAICS you covered them all well and I approve +1

I have one minimal comment to enhance an explanation that you have made, but that is up to you if you agree.

For Kinetic this really is step forward.

I'm a bit scared of SRUing this despite seeming absolutely correct.
Changing permissions/ownership always has an odd feel of "what if someone manually adapted for this problem".
We have had this in the past and depending on the uncertainty level we guarded the changes by evaluating the situation if it matches the expected one (in this case perm/ownership) but back then all changes were in maintainer scripts, here with conf files and such this would not work.
Did you discuss the SRUability of this with anyone on the SRU team already?
