Subject: [PATCH] mkdumprd: replace lz4hc with lzma for better compression in
|
|
squash image
|
|
|
|
Among the compression algorithms currently enabled in RHEL-10,
|
|
erofs+lzma has a higher compression ratio than lz4hc, this patch
|
|
will replace it with lzma.
|
|
|
|
Testing shows when using erofs+lz4hc in RHEL-10, the size of the
|
|
initramfs generated for local dump is 47M, and the size for nfs
|
|
dump is 57M. After using lzma, the size is reduced to 39M and 45M.
|
|
This is very closely compared to the 38M and 44M when using
|
|
squashfs+zstd.
