We are migrating packages that meet below requirements:
1. using `callPackage`
2. called path is a directory
3. overriding set is empty (`{ }`)
4. not containing path expressions other than relative path (to
makenixpkgs-vet happy)
5. not referenced by nix files outside of the directory, other
than`pkgs/top-level/all-packages.nix`
6. not referencing nix files outside of the directory
7. not referencing `default.nix` (since it's changed to `package.nix`)
8. `outPath` doesn't change after migration
The tool is here: https://github.com/Aleksanaa/by-name-migrate.

Subject: [PATCH 3/4] libbacktrace: Support multiple build id directories

gdb supports multiple debug directories separated by colons:
|
||
https://github.com/bminor/binutils-gdb/blob/fcbfb25dcca625a7f999ec51d48b6fc3a32123c3/gdb/build-id.c#L136-L142
|
||
|
||
This is useful for example when using dwarffs in addition
|
||
to debug data installed using distribution’s package manager.
