Question: why allow_other is need for auto_mount

[sirloon]

Hi, I've been playing around with fuser, specially the auto_unmount option which I'm interested in. I'm not sure though why allow_other is automatically added to the options when auto unumount is set:

fuser/src/session.rs

Line 81 in 39d4177

modified_options.push(MountOption::AllowOther);

If it goes through fusermount, why allowing access to "others" is required? I tested it without that option, it works as far I can tell, but I'm probably missing something there...

Thanks!
