I think so too.  An alternative for now is to use a kernel with the right disk
modules compiled in.

When multiple file propagation is included we could look at supporting this
outright since it's a popular way to do kernels.  workspace-control can support
initrds, it would not be a stretch to add a particular initrd for the default
kernel option (where propagation is not an issue).

We're also planning on supporting bootable hard disk images soon (where one
could include whatever kernel/initrd that is necessary).
