Initrd: no reason it wouldn't work, although for anything related to the
boot process testing is a very good idea. If you test, you'd really want to
apply that printk patch I posted, it's too easy to accidentally get a silent
fallback to gzip or uncompressed. I wonder, perhaps such a printk could be
permanently added, at a low message priority?
Kernel itself: needs per-arch porting, but it's not advertised in kconfig
outside x86 so that's not a problem.
If you are knowledgeful about bootloaders on ppc64, sparc64, etc, such
information would be great.
Meow!

zstd initrd worked on sparc64/sun4u - Ultra 30:

Any chance we could get this initrd zstd support upstream?
