Yes, but isn't initrd slow to copy from the boot media (caches off, simple byte by byte copy)?

Could we do with an initrd instead of an image? I mean, busybox + small set of tools is probably enough for validation, and will be quite small.
There is inherent bloat as soon as we add a package manager in the mix
Right, current thoughts after some IRC discussion are:
- busybox
- no package manager
- max size of 30mb (without kernel)
- some further removal of packages
I think with this in place you will get a ~30mb compress rootfs, we could even go further if necessary.
Sounds good, but that does not answer the question of whether it should be an initrd, a file system image, or both.
I think having something available as an initrd image, or at least an option for this, would be extremely valuable because it lets you netboot the kernel+image without the need for NFS or for physically installing the image on the target system.
