Deploying with ironic-agent ramdisk built from fedora 21 cloud image fails

[Ramakrishnan G (rameshg87)]

When deploying in bios mode using ironic-agent ramdisk based on fedora cloud image 21, it gets stuck at this prompt:

ISOLINUX 6.03

Failed to load ldlinux.c32
Boot failed: press a key to retry

[Ramakrishnan G (rameshg87) (rameshg87)]

It seems uptil SYSLINUX 5.0, the binary isolinux.bin was standalone.

Starting from 5.0.0, it is dependent on more files:

    Package ldlinux.c32 along with isolinux.bin if it exists

    Starting from syslinux 5.00, isolinux.bin is dependent on
    ldlinux.c32 to boot for BIOS machine. syslinux > 5.00 is
    delivered with Fedora 21 cloud image which breaks the boot
    from ISO if ldlinux.c32 doesn't exist.
