Title:
Do not re-compress compressed kernel modules and firmware files
Status in initramfs-tools package in Ubuntu:
In Progress
Bug description:
initramfs-tools decompresses kernel modules and firmware files before
putting them into the initramfs. This has several drawbacks:
* The compressed kernel modules and firmware files are probably compressed
with a higher level. So recompressing them in the initramfs (default: zstd -1)
will increase the size.
* Decompressing and compressing these files during mkinitramfs will take time
* The size of the decompressed initramfs will be bigger. That size is needed
in memory during boot.
So put compressed kernel modules and firmware files in an uncompressed
cpio instead. To make this change have an impact the files need to be
shipped compressed:
* kernel modules: bug #2028568
* firmware files: bug #1942260
