Bug Description

Got this warning on Kinetic, Mate flavor:

Paramétrage de dpkg (1.21.7ubuntu3) ...
dpkg: warning:

 This system uses merged-usr-via-aliased-dirs, going behind dpkg's
back, breaking its core assumptions. This can cause silent file
overwrites and disappearances, and its general tools misbehavior.

 See <https://wiki.debian.org/Teams/Dpkg/FAQ#broken-usrmerge>.

I thought we patched that warning out. Do not read it :D

Notably this is the only supported layout.

Also you probably don't want to run devel proposed, that's a recipe for disaster.
