The comment in lib/systems/default.nix for uname.processor indicates that it
should match `uname -p`. I tried that command and found that it reports
`unknown` on all of these machines:
- `x86_64-linux`
- `aarch64-linux`
- `mips64el-linux`
- `powerpc64le-linux`
The command `uname -m` reports the expected value on all of the above.
I think the comment is wrong. So I fixed it.
This is particularly useful for disabling modules defined in a flake.
Example:
disabledModules = [ "${flake}/modules/mymodule.nix" ];
Previously, absolute string paths were internally prepended with `modulesPath`,
which caused the module filtering to fail.
Recent commit 59356f11c1 ("perlPackages: Ensure all packages have a
license", 2022-08-22) added a license field to Perl packages where the
license was missing. The above mentioned packages got assigned
`unfreeRedistributable` license, which is not precise and makes all
packages depending on them unbuildable without `NIXPKGS_ALLOW_UNFREE`.
The packages actually have a license which SPDX calls
BSD-4-Clause-Shortened (https://spdx.org/licenses/BSD-4-Clause-Shortened.html).
In this commit, we add this license to the list of allowed licenses
and change the license field of the mentioned packages.
Closes #188103
In Nixpkgs, we assume that the "config" field is a canonicalized GNU
triple. I noticed that non-canonical values were being used here,
because the pkgsCross.mips64el-linux-gnu triples did not contain the
vendor field, but the pkgsCross.mips64el-linux-gnu.pkgsStatic did.
Here, I've run all the MIPS triples in lib.systems.examples through
config.sub to canonicalize them. I think this will avoid nasty
surprises in future.
Tested by building Nix and the bootstrap files for
pkgsCross.mips64el-linux-gnu.
More nixpkgs code such as `boot.initrd.systemd.emergencyAccess` defines
options that takes hashed passwords, so move the type definition from
modules/ into lib/.
The type definition itself stays unchanged.
`m` must always be an attrset at this point. It is basically always
evaluated. This will make it throw when any of the attrs is accessed,
rather than just `config`. We assume that this will improve the error
message in more scenarios.
