Good point - in general.
I do believe, however, that a lifespan of 7 years for perlmodule.mk
isn't particularly short.
The reason for deprecating perlmodule.mk is that more Perl build systems
emerged than the initially implemented MakeMaker one, and I was not able
to find a way for perlmodule.mk to (elegantly backwards-compatible)
support both those upstream build systems.
I prefer replacing single snippets over bumping epoch (the /1/ in
current path) whenever possible, to affect as few users as possible with
I write "I" in the above even if we are multiple people working on CDBS,
as it is something we haven't discussed as a team.
I welcome input on this - both from team members and users (and hey - do
consider step up and join the team: you need not be an übergeek or even
be official Debian Developer to join, just have a passion in CDBS and a
occasional bit of spare time).
Would it perhaps help to include in the warning a promise on how long
the deprecated snippets will be kept alive? How long should that be?
I suggest keeping this bugreport alive to discuss also what things might
be interesting for an epoch bump.
