* gen_funcs.sh: use stat(1) to check free disk spaceVladimir Vrzić2023-07-281-12/+14
| | | | | | | | | By using stat(1) to get free disk space we avoid tricky parsing of df(1) output. Signed-off-by: Vladimir Vrzić <vvrzic@gmail.com> Closes: https://github.com/gentoo/genkernel/pull/22 Signed-off-by: Sam James <sam@gentoo.org>
* Replace use of `which`Sam James2023-07-271-2/+2
| | | | | | | We're trying to phase it out as it's non-portable. Use bash's `type -P` where available (preferable as it avoids user functions) or `command -v` if POSIX. Signed-off-by: Sam James <sam@gentoo.org>

* Refactor (compressed) kernel module handlingThomas Deutschmann2021-09-091-0/+72
| | | | | | | | | | | | | | | | | | | | | | To support a specific module compression algorithm, two things are needed: Used depmod utility on host system building the kernel must support chosen module compression algorithm to generate proper modules.dep file or genkernel would be unable to read module dependencies when copying modules to initramfs. At runtime, used modprobe utility must be able to handle chosen module compression algorithm or modules would be unloadable. To address the first requirement, genkernel will now check if used kmod utility on host system supports chosen module compression algorithm. To address the runtime requirement, this commit will switch from BusyBox's modutils implementation to kmod because BusyBox does not support ZSTD compression (yet).
