commit: 2073571d34ad5efcd6d4ec4db0914e774ca69a19 Author: Andrew Ammerlaan <andrewammerlaan <AT> gentoo <DOT> org> AuthorDate: Mon Aug 5 19:13:28 2024 +0000 Commit: Andrew Ammerlaan <andrewammerlaan <AT> gentoo <DOT> org> CommitDate: Wed Aug 7 08:58:39 2024 +0000 URL: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=2073571d
kernel-install.eclass: use dist-kernel_get_module_suffix to find compression Adjusts kernel-install_compress_modules to use the new function dist-kernel_get_module_suffix. This makes no functional difference at the moment since gentoo-kernel-bin is the only consumer and it has XZ compression in the config. Still this makes it possible to compile alternate prebuilt kernels with alternate module compression support, and may in the future help to support gzip and zstd module compression in gentoo-kernel-bin.
