Bug#877418: dh-strip-nondeterminism: kills clojure performance

No problem, great to see more people adding their thoughts! :)

Mmm, which is a completely fair assumption. See also:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=804339 !

In the abstract, I would agree; it is "just" a packaging problem that
we've caused ourselves.

However, do we really want to maintain a list of ".class" → ".clj"
mappings to hack around, essentially forever? :)

Further to this, in an ideal world, strip-nodeterminism should (and will
not!) exist. Indeed, I love to *remove* handlers/features from it as they
get merged upstream.

*Very* quick thoughts here: could some variant of a) be merged
upstream…? Perhaps upstream could move to a hash-based system instead
of using timestamps? eg. encoding the SHA1 of the file in the filename.


Best wishes,
