The man pages Some systems (Linux for one, I think) have a 'user' mount flag, to enable ordinary non-root users to mount devices. > mount(2) tell me, that the mount syscall needs superuser privilege. > But I don't want those users to be superusers. But I guess, if having the above functionality, mount would have to be setuid for it to work. Perhaps there is some good reason why FreeBSD (and Net, Open?) don't have this feature? Er, OpenBSD does. By default users cannot do mounting. But you can use a sysctl to enable it. For a number of security reasons, by default you do not want it enabled. -- This space not left unintentionally unblank. deraadt@openbsd.org www.OpenBSD.org -- We're fixing security problems so you can sleep at night.
