blocking issue with hwdata

[colemickens]

I'm confused.

wlroots wants hwdata, can't find it via pkg-config.

so I bump hwdata, and now pciutils can't find pci.ids from the hwdata package.

needs more investigation.

I don't get it. If I build hwdata, I get:

/nix/store/2x9s14w68zg86q7ha06lblz9npyjabjc-hwdata-0.364

but if I try to build pciutils, I get:

cp: cannot stat '/nix/store/7cbw62w3a6lh1rxxb982j99h42wkrpcd-hwdata-0.364/share/hwdata/pci.ids': No such file or directory

why is it using the wrong output path?

um what?

[colemickens]

I assume this has something to do with hwdata's use of outputHash...

[colemickens]

is this a nix bug?? https://github.com/NixOS/nix/issues/7148

[colemickens]

... I don't think hwdata can be a FOD anymore...

[colemickens]

Looks like this was already fixed in staging, where the FOD was indeed dropped with a version bump.
