mksquashfs allows to tweak many compressions parameters. Currently they can't be changed from kmenu. Leaving out potential space savings. This adds the option to enable a set of predetermined compression options. This option is enabled by default for lz4 since lz4 currently implicitly added the extreme to it in the makefile. So this aids in keeping backward compatibility.

Use options to increase compression ration as much as
|
|
possible, like using architecture-specific options, at
|
|
the cost of time when assembling the filesystem image.
|
|
|
|
For example:
|
|
- with gzip and lzo, use -Xcompression-level 9
|
|
- with xz use arch-specific bcj (branch-call-jump) filters
|
|
- with zstd use -Xcompression-level 22
|
|
- and more
