One could argue that the behavior of mount(8) (automatically trying all filesystem types) is the actual bug, and that its "auto" mode should restrict itself to using filesystems that are actually suitable for use with the current media. (Many filesystem types, EROFS included, could then be defined as supported only on non-removable media by default.)

Alternatively, the filesystem driver may itself verify that the media type is suitable before even reading the superblock.

(Personally I would love it if we could just use lklfuse for all filesystems on removable media… But it looks like nobody support it.)
