My guess re. debhelper is the same. Are we sure all the builder modules can safely be used in parallel mode? I'm not sure :) Probably we'd have to test this if we want it. If so, I guess it is time to try and employ it. Hm ... do we know if this is actually helpful? While parallel building is nice and everything, my pure guess is that it doesn't help alot, if all, for most of our tiny packages. (And most of the time is used for chroot setup/teardown, installing build deps, later lintian, ...) The time difference should be another test parameter :) Cheers, gregor -- .''`.

(And most of the time is used for chroot setup/teardown, installing build deps, later lintian, ...) The time difference should be another test parameter :) Right. Indeed, building libfile-mimeinfo-perl now takes 12.1s total, including chroot setup/teardown, with pre-populated package cache. Enabling --parallel results in 12.4s build time. So, Jonathan, why are you requesting enabling parallel builds for libfile-mimeinfo-perl? signature.asc Description: Digital signature

[0] Well, we could do a nice mass-change, if we want. What do others think? Personally I would prefer to keep the simple three-line debian/rules makefile for our easy packages whenever possible. Otherwise we probably also would want to modify dh-make-perl. Regards, Salvatore -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

I completely agree. I've only filed such wish list bugs when I've been submitting a patch for something else at the same time. I haven't read any existing threads to find out why it's non-trivial to change the default, I shall do some reading.
