# Note: This profile does not specify an attachment path because it is
# intended to be used only via "Px -> child-pager" exec transitions from
# other profiles. We want to confine the pager(1) utility when it
# is invoked from other confined applications, but not when it is used
# in regular (unconfined) shell scripts or run directly by the user.
