Summary: Cannot mount if rootfs is an image

Initial Comment:
I use an image as my lxc rootfs. If i try to mount something via lxc.mount.entry or using a fstab-file with lxc.mount i always get the error 'ignoring mount point XXX'.
I dumped rootfs->path in the mount_entry_on_absolute_rootfs-function in conf.c which is set to the name of the image and not to the value of lxc.rootfs.mount so it seems your currently can not use any mount points if your rootfs is an image file.

Message:
Yes, that's right. I think the man page is not up-to-date.

Message:
Just for curiosity i used the path of the image instead of the target
directory in my mount points and that is working. So the statement in the
man page "If the rootfs is an image file or a device block and the fstab is
used to mount a point somewhere in this rootfs, the path of the rootfs
mount point should be prefixed with the /usr/lib/lxc/root default path or
the value of lxc.rootfs.mount if specified." is wrong.
