Installing f2fs for R7800 Hnyman build?

What am I missing here? It appears it's not compatible?

Packages for kmod-fs-f2fs found, but incompatible with the architectures configured

You can't install kmods from the official repo to private builds.Too strict checksums.

Thanks for the info. Is there any way to format F2FS file systems with your build?

do it on some other device ?

Not to my knowledge.

But you could pretty easily take my build config and build script and compile your personal firmware containing just the packages (like filesystems support) that you need.
See message #2 in my build thread. (I use the process semi-annually to move to the newest Ubuntu and start fresh)

I'd love to dive into that when I've got some free time. Thanks!
