You say
"If a sysadmin trusts the users enough, or can ensure through other
measures, that system processes will never enter non-privileged mounts,
it can relax the last limitation with a "user_allow_other" config
option. If this config option is set, the mounting user can add the
"allow_other" mount option which disables the check for other users'
processes."
What config option, where?
