How does validation work in EROFS for files served from fscache and that

nevermind my last question, I guess it would still go through the block
device in EROFS.
This is clearly a point in favor of a block device approach that a
stacking file system like overlay or composefs cannot achieve without
support from the underlying file system.
nevermind my last answer,
I was thinking with Amir's advice, you could just use FUSE+overlayfs option
for this. I wonder if such option can meet all your requirements (including
unprivileged mounts) without increasing on-disk formats in kernel to do
unprivileged mounts.
If there are still missing features, you could enhance FUSE or overlayfs.
