This is a waste of time. I'm extremely glad Jakub took the time to answer and state his position against Jenkins where people like me read the ML and just did their best to forgot what they just read instead. I'm only afraid that more time wasted in such matters is only going to demoralize and deter the contributors who support sane options that go against the general FOSS popular consensus (busybox vs coreutils, musl vs glibc, runit/openrc vs systemd, etc.) and ultimately make alpine yet another GNU/Linux distribution.

Fair enough. I didn't mean to attack Roberto in particular. I understand that having QA on all archs is a wishable goal, but QA on x86_64 alone should already catch the biggest issues.

I never understood why redmine has been used. AFAICT it's an artefact of the early infancy of the distribution, and is an exception rather than a rule.

Improving test coverage for others archs is work indeed, but I'm afraid it's premature at this point. We just added the support for functionality tests in abuild literally weeks ago; and supporting the other archs in QA isn't going to be a trivial task. There is simply no CI system t I know that does not suck, and I evaluated as many as I could find about 6 months ago.
