12:34 < dongcarl> luke-jr, wumpus: Just as a short update: Guix needs #20019, and  #19683, then the macOS build will have a clean enough patchset for review.

12:35 < dongcarl> Also, luke-jr I'd love to know what troubles you're running into w/re running Guix on your system. They sound like installation problems and are most likely solvable
12:37 < wumpus> dongcarl: good to know!
12:37 < dongcarl> I _could_ hack around the need for #20019, and #19683, but I want to use this as an opportunity to make our build system/toolchain more robust.

12:40 < cfields> +1 for that, this work is fleshing out some things that needed to be fixed.
12:43 < luke-jr> dongcarl: I was having trouble figuring out where to start more or less
12:43 < luke-jr> dongcarl: IIRC there was a hash I had to set/change somewhere, but I couldn't find it
12:43 < dongcarl> sec, pulling up docs!
12:44 < luke-jr> looking at my files, in gnu/packages/bootstrap.scm
12:45 < dongcarl> Oh where did you see that you needed to change a hash? Is this the Guix Manual?
12:45 < luke-jr> no, AFAIK Guix only has binary / trust-based documented
12:46 < luke-jr> in fact, I'm not sure anyone has ever done a bootstrap without trusted third-party binaries
12:46 < dongcarl> Building from source is also documented: https://guix.gnu.org/manual/en/html_node/Requirements.html, I semi-regularly build Guix from source to test changes
12:47 < luke-jr> that's the Guix software itself, not the packages
12:47 < dongcarl> Which packages are you talking about specifically?
12:49 < luke-jr> I think I was trying to do ./pre-inst-env guix build bootstrap-tarballs
12:51 < dongcarl> luke-jr: And then what happened?
12:52 < luke-jr> I don't recall - this was several months ago
12:52 < luke-jr> it may be more productive to start from scratch? :/
12:54 < dongcarl> Sure, I'll run through it myself and see if there are any hiccups, it may very well be that you saw it download `bootstrap-binaries` which is its reduced binary seed of 130MB or so, if it was downloading other things, you might have needed the `--bootstrap --no-substitutes` flags. In any case, I'll go through the guide again and make sure things
12:54 < dongcarl> work properly
12:54 < luke-jr> I won't let it download bootstrap-binaries
12:55 < luke-jr> dongcarl: want to walk me through it? ;)
12:56 < dongcarl> I'd be happy to!
12:56 < luke-jr> I guess first I git clone https://git.savannah.gnu.org/git/guix.git ?
12:56 < dongcarl> (got something in an hour tho)
12:56 < dongcarl> luke-jr: You can also install from gentoo repos I think
12:56 < dongcarl> just emerge guix
12:57 < luke-jr> IIRC that uses binaries
12:58 < luke-jr> it was also removed in January
12:58 < dongcarl> Hm, lemme poke in gentoo repos
12:58 < dongcarl> Oh waht
12:58 < dongcarl> Oh it was moved to nix-guix ovelay?
12:59  * dongcarl kinda clueless about gentoo
13:00 < luke-jr> glancing at nix-guix overlay, it's using binaries
13:01  * dongcarl looking
13:02 < dongcarl> you mean in `copy_boot_guile_binaries`?
13:02 < luke-jr> yes, at least there
13:02 < luke-jr> besides, I don't want Guix to have root access
13:03 < luke-jr> and I suspect this would even if source-based do a system-wide install of it
13:05 < dongcarl> You can install Guix as an unprivileged user for sure
13:05 < dongcarl> Sorry, not sure what you meant by "and I suspect this would even if source-based do a system-wide install of it"
13:05 < luke-jr> emerge/the overlay
13:07 < dongcarl> Right. Okay, give me some time to play with Gentoo in a VM and get back to you on your specific request. However, I want to know how you're running gitian/one of its backups as an unprivileged, non-system-wide thing
13:07 < dongcarl> s/backups/backends
13:08 < luke-jr> IMO there's no reason to do anything Gentoo-specific here ☺
13:08 < luke-jr> KVM does not require root
13:08 < luke-jr> gitian runs KVM with Ubuntu presently
13:10 < dongcarl> KVM does not require root specifically because it's running as a kernel module tho, no?
13:10 < luke-jr> the virtualization layer does have kernel support, but that's beside the point?
13:10 < luke-jr> I mean, literally everything does - any syscall uses the kernel
13:12 < dongcarl> Sure, let me give it a go, do some digging, and get back to you. I want this to be usable! :-)
13:12 < luke-jr> could presumably rework the gitian builds to use Guix instead of Ubuntu, but yeah, would be better to get something that is fully trustless
