If a bls directory is empty, eclean-kernel fails with a KeyError. This can happen when too many kernels build up and the /boot partition is filled to the point that writing the initramfs fails. Fixes gentoo#60 e.g. File "/home/peter/eclean-kernel/.venv/bin/eclean-kernel", line 10, in <module> 12:42 [54/433] sys.exit(setuptools_main()) ~~~~~~~~~~~~~~~^^ File "/home/peter/eclean-kernel/ecleankernel/__main__.py", line 391, in setuptools_main sys.exit(main(sys.argv[1:])) ~~~~^^^^^^^^^^^^^^ File "/home/peter/eclean-kernel/ecleankernel/__main__.py", line 236, in main kernels = layout.find_kernels(exclusions=exclusions) File "/home/peter/eclean-kernel/ecleankernel/layout/blspec.py", line 130, in find_kernels kernels[(ver, "bls")].all_files.append( ~~~~~~~^^^^^^^^^^^^^^ KeyError: ('7.0.1-gentoo-dist', 'bls')
