From 26e60de5c6aa57c144041583935ccb5d923fc4f9 Mon Sep 17 00:00:00 2001 From: Peter Wu Date: Fri, 1 Feb 2019 15:40:53 +0100 Subject: [PATCH] mount.8: clarify (no)suid behavior on file capabilities Clarify that the nosuid option also affects file capabilities and that it only limits execution of programs. (setgid on directories still inherit the group regardless of the nosuid option.) The new text is taken from the mount(2) manual page from the man-pages project.
