I think the tencency is to mount untrusted file systems over FUSE, due to the realisation that file system code wasn't designed with malicious file system images in mind (remember? the time that code got written, you had one hard disk firmly screwed into your beige box computer), and on the hope that something exploding in user space might be less devastating that having it explode in kernel space... For a rough impression, cf. e.g. here [1] It's a timid first step to remove one of those skeletons from beneath the bed (or a move towards a microkernel, depending on your current mood ;-) Cheers [1] https://lwn.net/ml/linux-kernel/20180523234114.GA3434@thunk.org/ - t
