@zhenech well, yes, I do have #shellcheck wired in a bunch of builds, just not for all packages I'm touching today, from multiple machines, not all of them having proper editors/hooks/confs deployed. That's why I'm enjoying #lintian as the last line of defense before wasting time.
I must reckon that I like #lintian very much sometimes: caught at least two instances of stupid shell syntax errors in various scripts, before I threw those udebs into debian-installer then debian-cd builds.
