commit 9c77679cadb118c0aa99e6f88533d91765a131ba upstream. For newer versions of Syslinux, we need ldlinux.c32 in addition to isolinux.bin to reside on the boot disk, so if the latter is found, copy it, too, to the isoimage tree. Signed-off-by: H. Peter Anvin <hpa@zytor.com> Cc: Linux Stable Tree <stable@vger.kernel.org> Signed-off-by: Willy Tarreau <w@1wt.eu>
