SubjectRe: [PATCH v3 0/8] Add support for ZSTD-compressed kernel and initramfs

So did I and a bunch of other folks. I for one run v1 since 2017 on
a bunch of boxes (amd64/BIOS, amd64/EFI, arm64, armhf), without a glitch
(not counting trying to boot zstd initrd _without_ the patchset :p).

I've tried v2 on all of the above configurations, v3 on all but armhf, v4 on
amd64/EFI -- all is fine.

Back in the days, folks reported success on IIRC ppc64, sparc64 and more.

(Obviously, initrd only on !x86.)

+zstd) compress="zstd -19 -v" ;;

I'm not sure if hard-coding -19 is always right. It's good for production
machines but slows down dev cycles.

But that's a matter for userland, not a problem with Nick's patchset.


Meow!
