Bug#389994: Found the bug, patch attached

[Tim Phipps <tim@phipps-hutton.freeserve.co.uk>]

The bug is in this section:

                if [ "${NFSROOT#:*}" = "$NFSROOT" ]; then
                        NFSROOT=${ROOTSERVER}:${NFSROOT}
                fi

The :* is the wrong way around so if $NFSROOT=192.168.0.4:/ the :*
pattern won't match (NFSROOT doesn't start with :) and so NFSROOT gets
turned into 192.168.0.4:192.168.0.4:/ which fails to mount. Changing the
pattern to *: works as (would %:*).

Cheers,
Tim.
