In reply to @asymmetric:matrix.dapp.org.uk
is there a reason why for the module system, we say "defining an option" instead of "setting an option"? I feel like i have to think a couple seconds every time i read definition/declaration, to remember what each means. this wouldn't happen with setting/declaration

Robert Hensing (roberth) wrote a proposal on changing that: https://github.com/NixOS/nixpkgs/issues/185234

I think it should be implemented as written. There's a pile of issues on module system docs, this is one of it.

@federicodschonborn:matrix.org@federicodschonborn:matrix.org changed their profile picture.00:13:04
@fsbof:matrix.orgfsbofI've been upgrading NixOS. On the good side, I've had options that other distros didn't offer but I still broke stuff! Badly! I finally tracked down that "virtualisation.libvirtd.qemu.ovmf.package = pkgs.OVMFFull" updated the version of OVMF_CODE.fd which subsequently caused virtual domains using UEFI to no longer successfully boot. This is likely related to a change in size of the nvram, and starting the domains with the virsh --reset-nvram option allowed them to boot. I also needed to then go into the UEFI config and update the display resolution in order to see the actual boot process. This took hours to work through - is it worth documenting anywhere for others because I couldn't find much. Also I am still on NixOS 22.05 - Trying to get to 23.05, so my issues maybe 'out-of-date' but they got me! 10:00:05
@infinisil:matrix.orginfinisil fsbof: Sounds like that should be added (if it's not already) to the 23.05 release notes. There's a breaking changes section 10:02:31
@fsbof:matrix.orgfsbofI did look in the release notes and could only find two mentions of OVMF changes in 22.11 and 21.1110:06:09
@fsbof:matrix.orgfsbofI also managed to break it with out needing to upgrade the NixOS version - just by add the line above to configuration.nix in 22.05 when it previously didn't exist.10:08:34
@fsbof:matrix.orgfsbofI guess what I am saying is it could happen in two situations10:08:56
@infinisil:matrix.orginfinisilMaking a PR to the release notes for both cases would be good imo10:09:42
@infinisil:matrix.orginfinisilFor the the first release where each became a problem10:10:07
@fsbof:matrix.orgfsbofCan you guide me through the process - happy to do it, just haven't done it before10:10:13
@raitobezarius:matrix.orgraitobezariusPlease include details about how did you narrow down to this, it's complicated when release notes misidentify the root cause10:10:32
@raitobezarius:matrix.orgraitobezariusWe have similar OVMF bumps for 23.11 and they will be breaking a lot of shit without any recourse I think because EDK2 maintainers seems to have broken a lot of stuff with OpenSSL 3 bumps10:11:21
@fsbof:matrix.orgfsbof raitobezarius: Yes - I am concerned that 'getting it working' isn't really the same as finding a problem! My configuration could have been broken to start with! It has been a steep learning curve but very worth it. 10:12:30
@infinisil:matrix.orginfinisil

fsbof: On my phone right now, but release note sources are here: https://github.com/NixOS/nixpkgs/tree/master/nixos/doc/manual/release-notes

Github allows you to edit files right online and then make a PR for that: https://docs.github.com/en/repositories/working-with-files/managing-files/editing-files#editing-files-in-another-users-repository

10:12:47
@raitobezarius:matrix.orgraitobezariusI'd recommend NixOS Wiki personally for "unbreaking recipes" than release notes10:12:57
@raitobezarius:matrix.orgraitobezariusEspecially when touching older ones10:13:02
@raitobezarius:matrix.orgraitobezariusWe usually archive older release notes after a while10:13:09
@fsbof:matrix.orgfsbofsuggestion - how about I write something up - put it in the Wiki and let you two see what you reckon?10:13:52
@fsbof:matrix.orgfsbofIf it is worth the PR I can go from there10:14:09
@infinisil:matrix.orginfinisilThe NixOS wiki shouldn't really be used anymore though, it's not maintained at all10:14:13
@infinisil:matrix.orginfinisilIf not the release notes, nix.dev could be an alternative10:14:35
@infinisil:matrix.orginfinisilWhich is maintained by the docs team10:15:19
@raitobezarius:matrix.orgraitobezariusI'm not sure all the unbreaking recipes will be maintained / accepted by nix.dev, but if so, that's great news10:16:20
@infinisil:matrix.orginfinisilAs a member of the docs team, I think having a page for that would be fitting :)10:16:51
@infinisil:matrix.orginfinisilAnd actually there is already: https://nix.dev/recipes/troubleshooting10:17:20
