There's an keyError with 6.13.1-gentoo-dist and bls

[samip5]

That error makes no sense to me?

I'm using ugrd.

I get the same error and the "solution" mentioned in the comment above doesn't apply, as eclean-kernel is emerged with zstd.

I don't know if this helps anyone, but I managed to hack the script working for me.
Problem was that I somehow got 2 kernel paths which were empty
/boot/efi/f9e417064ca162bc1b04a60c644c3fae/6.17.3-gentoo-dist was one of them and because of that in blspec.py:130

                kernels[(ver, "bls")].all_files.append(
                    EmptyDirectory(dir_path))

kernels[(ver, "bls")] threw an exception.

"fixed" this by simply adding

+               if (ver, "bls") not in kernels.keys():
+                  kernels[(ver, "bls")] = k
                kernels[(ver, "bls")].all_files.append(
                    EmptyDirectory(dir_path))

in front and it cleaned up everything.

this test case provokes the problem I had and the "fix" from above lets this test case pass.

class BlSpecLayoutTests(unittest.TestCase):
....
    def test_find_no_kernels(self) -> None:
        with self.create_layout() as td:
            path = Path(td)
            blspath = path / f"boot/{self.machine_id}"
            ukipath = path / "boot/EFI/Linux"
            modules = path / 'lib/modules'
            os.remove(blspath / '1.2.1/linux')
            os.remove(blspath / '1.2.1/initrd')

            BlSpecLayout(root=path).find_kernels()

I did not look too deeply into the script, so I don't know if/what side effects this has. Maybe this can be used as a point of reference for a real fix, where some missing files don't break the whole script.
