> 1. Do you have strong tempering prevention guarantees built-in (beyond being immutable of course) or is that something people have to figure out outside of EROFS?

dm-verity is probably your best bet for this, which would let you use erofs, squashfs, or whatever other read-only filesystem you want. I've been pretty happy with dm-verity + squashfs in past projects, I'm sure erofs would work great too.

Signed verified images are fine of this (if users just trust the signature), I think later LWN will post the following LSF/MM FS track topics. The related stuffs discussed several times in several seperate topics.
