From d199d652c513a010145a5a0d4e64c96361b97bee Mon Sep 17 00:00:00 2001 From: Anthony Liguori Date: Wed, 6 Feb 2008 19:25:06 -0600 Subject: 9p: add support for sticky bit GDM gets unhappy if /var/gdm doesn't have the sticky bit set. This patch adds support for the sticky bit in much the same way setuid/setgid is supported. With this patch, I can launch X from a v9fs rootfs (although I quickly run out of fds in the server once gnome starts up).
