Re: kern/29360: vfs.generic.usermount and mount(8) general questions


Yes, vfs.generic.usermount was introduced later, because of security issues
that usermounts could cause. AFAIK the know security issues with
usermounts are fixed, but still it's better to have it disabled on systems
where it's not needed.

The main reason for not allowing user mounts by default is that it's
quite easy to make a system panic by mounting some (more or less) carefully
crafted media.
