Subject: [PATCH] switch_root.c: umount mount points we cannot move with MNT_DETACH
Date: Mon, 14 Nov 2011 14:11:01 +0100 [thread overview]
Message-ID: <1321276261-9165-1-git-send-email-harald@redhat.com> (raw)
From: Harald Hoyer <harald@redhat.com>
If a mount point cannot be moved to the new root, umount it with
MNT_DETACH, so that it is lazy umounted and does not show up in
/proc/mounts anymore.
