  Zstandard is an ideal compression algorithm with great performance for
this purpose. The kernel is still able to load firmware compressed using
XZ and ramdisks compressed with various other algorirthms.

Backported from IPFire 3.x as a3776d8aee67369dcff8ea091bc8b785dc2d6647.

Hello,

I disagree for reasons that I pointed out in the cover letter.

Xz is probably doing a fine job here.

If other people think we have enough space, I obviously don’t have a problem at all with Zstandard.
