Well, right, but that doesn't really address the issue.  Even if FILES
is defined in terms of ${base_libdir} or whatever, it's still not going
to match if fixup_perms() has shuffled things around in some random way.
I don't think there is any reliable way for fixup_perms() to find and
patch all the variables that might refer to paths that it has decided to
adjust.

Conversely, if FILES is defined in terms of ${base_libdir} and
do_install() puts the files there, you can change the value of
${base_libdir} to whatever you like and everything will "just work"
without the need for fixup_perms() to move anything.

As I mentioned somewhere else in this thread, micro has been using a
merged /usr for several years (but done the other way around, so
everything is installed into /bin and suchlike) and this has worked just
fine without the need for any fsperms magic.  I can't see any obvious
reason why the new-style /usr merge is fundamentally more difficult.
