Why the hell is your image so large? The image should contain the
kernel, and the minimal amount of drivers and software needed to
bootstrap the remote disks and continue startup. My old 32-bit NFS
images were around 2MB total. My current iSCSI images are just shy of
6MB, which is kernel, busybox, iSCSI initiator, and assorted drivers.
Even my install images, which are a fully functional system loaded into
a memory disk, used to install systems from a remote package repository,
aren't that large. Gentoo is around 65MB, and FreeBSD is under 40MB.
