From a85fb273c94648cbf20a5f9bcf8bbbb075f271ad Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Tue, 31 Jul 2012 01:14:12 -0700 Subject: vfs: Allow chroot if you have CAP_SYS_CHROOT in your user namespace Once you are confined to a user namespace applications can not gain privilege and escape the user namespace so there is no longer a reason to restrict chroot.
