https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=232021 --- Comment #13 from Allan Jude <allanjude@FreeBSD.org> --- (In reply to Oleg from comment #9) The difference is that unmounting has only one input, the filesystem you wish to unmount. Mounting is more dangerous. Sure bob is allowed to mount zroot1/tst, but the system call also allows them to mount zroot1/tst to /etc Now a filesystem the user controls, contains the password file, and that user is now root. That is why the FreeBSD vfs.usermount feature implements a sanity check, bob can only mount filesystems to directories they is the owner of. -- You are receiving this mail because: You are the assignee for the bug.
