Not at all. pam or whatever we transition via cooperation from dpkg,
would be kept compiling using the directories it currently uses, and
debhelper would simply move the objects on the .deb from «/» to «/usr»,
and create the compat symlinks. That means pam, and any plugins migrated
or not, would still be available in the current pathnames causing no
breakage. This part would be done automatically.

And as I've said elsewhere, removal of the compat symlinks would
require manual intervention (at the maintainer discretion), at some
later time, to modify the configured installation paths (which is
something that cannot be automated in debhelper, due to packaging
overrides and similar), at which point it can be decided whether to
declare say a local pam flag day, or add the needed Breaks and similar,
or add support to pam to look in both pathnames to avoid the two
previous items.

See my comment above, and josch reply.

Well if they did it poorly, no wonder, I guess.

I obviously disagree.

Did you miss the section in the mail you are replying where I mention
that f.ex. dpkg tools (dpkg, dpkg-divert, u-a) missing to then detect
file conflicts, or files disappearing on moves, or dpkg-deb -x (or tar)
destroying merged-/usr-via-aliased-dirs systems?

All these, including dpkg -S (which BTW also breaks after paths have
been moved, as when say bash ships as /usr/bin/bash, then dpkg -S will
also fail to find the expected /bin/bash), are currently affecting any
system being installed by the default installer, or ones having been
switched by the usrmerge hack.

The same can be said about my proposal, except that then dpkg is kept
in the loop, the transition is done safely by dpkg as part of individual
package upgrades, instead of having to use something off-band and as
disturbing as usrmerge during upgrade, on dpkg's back w/o any
cooperation from it…
