Title:
Ship kernel modules Zstd compressed
Status in linux package in Ubuntu:
Fix Committed
Bug description:
To reduce the size of the initramfs and also to speed up the boot (by
only decompressing the modules that are needed), please compress the
kernel modules. From size and speed perspective, either use zstd or
xz. I suggest to go with zstd -19.
This change is independent of the initramfs-tools version. Old
initramfs-tools versions will decompress the kernel modules before
putting them in the initramfs. New initramfs-tools versions will put
the compressed kernel modules into an uncompressed cpio archive (see
bug #2028567).
