Don't try to pivot to new ramfs if already running on one This patch allows the sysupgrade script to continue with the upgrade if openwrt is already running on a ramfs. This allows the use of the sysupgrade script as an _installer_ when running from an iso image. A user could boot the system from a bootable cd and invoke sysupgrade -n <URL> to write an image to the hard disk or CF.
