说明
eclean-kernel removes old kernels in Gentoo Linux. It cleans up kernel images, modules, and related files while preserving a specified number of recent kernels. Over time, /boot and /lib/modules accumulate old kernel versions from upgrades, consuming significant disk space. This is particularly problematic on systems with small boot partitions. eclean-kernel automatically identifies and removes old kernel files while protecting the running kernel and a configurable number of recent versions. The tool handles all kernel-related components including the kernel image, System.map, initramfs, config files, and module directories. It's safer than manual deletion as it understands kernel dependencies and prevents removing essential files.
