- This option compresses the kernel modules when 'make
- modules_install' is run.
- The modules will be compressed either using gzip or xz depend on the
- choice made in "Compression algorithm".
+ Compresses kernel modules when 'make modules_install' is run; gzip or
+ xz depending on "Compression algorithm" below.
- module-init-tools has support for gzip format while kmod handle gzip
- and xz compressed modules.
+ module-init-tools MAY support gzip, and kmod MAY support gzip and xz.
- When a kernel module is installed from outside of the main kernel
- source and uses the Kbuild system for installing modules then that
- kernel module will also be compressed when it is installed.
+ Out-of-tree kernel modules installed using Kbuild will also be
+ compressed upon installation.
- This option provides little benefit when the modules are to be used inside
- an initrd or initramfs, it generally is more efficient to compress the whole
- initrd or initramfs instead.
+ Note: for modules inside an initrd or initramfs, it's more efficient
+ to compress the whole initrd or initramfs instead.
- This is fully compatible with signed modules while the signed module is
- compressed. module-init-tools or kmod handles decompression and provide to
- other layer the uncompressed but signed payload.
+ Note: This is fully compatible with signed modules.
+
+ If in doubt, say N.
