[15:11:41] <shdubsh>	 moritzm: mtail rc35 won't install due to auto-added dependency on init-system-helpers >= 1.51.  is there a way to tweak this version or is it dist-specific?
[15:15:26] <moritzm>	 did you rebuild it for buster-wikimedia or was it imported from sid?
[15:16:26] <shdubsh>	 I rebuilt it for buster.
[15:17:03] <moritzm>	 was that on deneb, is the build log in your home?
[15:18:09] <moritzm>	 it generally should not cause any issues, as buster has 1.56 and it's installed universally
[15:18:29] <moritzm>	 probably it was missing previously, but the clean rebuild now properly added the dependency
[15:19:03] <shdubsh>	 I didn't capture a build log.  I should start doing that :)
[15:19:55] <shdubsh>	 yes, on deneb
[15:19:58] <moritzm>	 it's done automatically :-)
[15:20:10] <shdubsh>	 oooh, where?
[15:21:33] <volans>	 $package_name.build in your home
[15:21:43] <moritzm>	 it's in fact not there, pdebuild creates it by default as .build, how did you invoke the build?
[15:21:58] <shdubsh>	 sudo -E cowbuilder --build ../mtail_$(dpkg-parsechangelog -n1 -SVersion).dsc
[15:22:38] <volans>	 why sudo?
[15:23:02] <shdubsh>	 volans: what I was shown during onboarding :)
[15:23:12] <moritzm>	 you can simply run "DIST=buster pdebuild" in the source tree
[15:23:27] <moritzm>	 this will create the log file Riccardo mentioned
[15:23:31] * shdubsh updates personal notes
[15:24:01] <moritzm>	 on which host did it fail to install because of init-system-helpers >= 1.51? that's surprising, would like to have a look
[15:24:10] <shdubsh>	 fermium
[15:24:46] <moritzm>	 but fermium is jessie, and you rebuilt it for buster?
[15:25:13] <moritzm>	 which component did the build get imported to?
[15:25:39] <shdubsh>	 yes, the needed golang dependencies aren't in any other dist.  
[15:26:10] <shdubsh>	 in debian, rc35 is only in sid
[15:26:27] <shdubsh>	 I invoked cowbuilder with DIST=buster
[15:28:03] <moritzm>	 ok, I see what you
[15:28:09] <moritzm>	 ok, I see what you're trying to do now
[15:28:22] <shdubsh>	 pdebuild completed -- works awesome. thanks!
[15:28:24] <moritzm>	 there's a way around this:
[15:28:32] <moritzm>	 the pdebuild build will have the same issue
[15:29:13] <moritzm>	 it's not really an issue, you're simply trying to do something unsupported (building for a more recent distro and then trying to install this for an older release) :-)
[15:29:21] <moritzm>	 but we can work around it:
[15:30:34] <moritzm>	 at least I think we can, having a quick look
[15:31:07] <shdubsh>	 another thought was to import the needed golang libs into jessie and stretch then see if it builds.  would that be a better option?
[15:31:34] <moritzm>	 that's a rabbit hole we don't want to enter :-)
[15:31:49] <cdanis>	 you know what they say, ask 3 Debian Developers, get 9 answers, plus also 'Choice 10: None Of The Above'
[15:32:29] * shdubsh was worried about that being a rabbit hole
[15:32:42] <moritzm>	 shdubsh: do we have rc35 installed anywhere already?
[15:32:50] <moritzm>	 want to have a quick look at the current deb
[15:32:50] <shdubsh>	 no
[15:32:55] <moritzm>	 ok
[15:33:09] <volans>	 cdanis: also the feeling of stability from an rc35 :D
[15:34:17] <moritzm>	 ok, so:
[15:35:21] <moritzm>	 the reason this dependency got added it because of a feature added in debhelper 11 for handling sysvinit init which are disabled by default: 
[15:35:22] <moritzm>	 https://tracker.debian.org/news/899696/accepted-debhelper-111-source-into-unstable/
[15:35:32] <moritzm>	 dh_installinit: Support a new --no-enable parameter to setup the
[15:35:33] <moritzm>	      init script with the "defaults-disabled" and add the proper
[15:35:35] <moritzm>	      versioned dependency on "init-system-helpers (>= 1.51)", which is
[15:35:36] <moritzm>	      the first (functional) version with support for
[15:35:57] <moritzm>	 mtail rc35 ships a systemd unit, so the init script is of no concern for us
[15:36:21] <moritzm>	 if you look at the debian/control file of rc35 on deneb
[15:37:02] <moritzm>	 you see ${misc:Depends}
[15:37:15] <moritzm>	 this is a macro that gets expanded with any dependency added by means of debhelper
[15:37:57] <moritzm>	 init-system-helper itself
[15:38:04] <moritzm>	 is an "essential" package
[15:38:13] <moritzm>	 i.e. it's automatically present on every Debian system
[15:38:26] <moritzm>	 and you can only delete it when confirming a scary prompt
[15:38:42] <moritzm>	 so what debhelper added there is only about the fact that you need >= 1.51
[15:38:53] <moritzm>	 but you only need this if you use sysvinit
[15:39:46] <moritzm>	 as such, you can simply drop ${misc:Depends} from the package and after a reboot it should install just fine on jessie/stretch (given that the rest of the package is a static ELF file as created by Go)
[15:40:29] <moritzm>	 and make a note to debian/changelog that we remember the next time we import rc75 (they sure are conversative about declaring it not done :-)
[15:40:53] * jayme giggles on "after a reboot"
[15:41:06] <moritzm>	 oh :-)
[15:41:12] <moritzm>	 rebuild ofc
[15:41:26] <volans>	 or reboot while rebuilding... who knows :D
[15:42:46] <jayme>	 begs for some "It's A Trap!" meme
[15:43:15] <shdubsh>	 ok, I will try dropping misc:Depends.  what does this change mean for the version string?  +wmf1?
[15:44:58] <moritzm>	 +wmf1 sounds good given that we only rebuild this on buster (or use the more canonical +deb10u1 which we use for packages which are rebuild across distros), both works fine
[15:45:56] <shdubsh>	 great, thank you! :)
