Use sanhook to expose ISO as block device during kernel/initrd boot
The CPIO-embedded initrd approach failed (too large for iPXE memory).
Instead, use iPXE's sanhook to connect the ISO as a SAN block device
before booting with kernel/initrd. The installer finds the ISO on the
SAN device while we retain control over kernel parameters.
