... and you'd need to build your own kernel on these platforms in any
case, because Debian kernels (like those in most distributions) are
heavily modularized, and can't see a disk or mount the root filesystem
without help from user-space anyway (CONFIG_SATA_AHCI=m,
CONFIG_EXT4_FS=m and the equivalents for other drive interfaces and
tiny-initramfs, mentioned elsewhere in this thread, seems an excellent
candidate for embedding in a kernel that doesn't need a "full-fat"
initramfs: it's around 16K when statically linked to a small libc, and
is configured via the kernel command-line (to mount the root) and the
root's /etc/fstab (to mount /usr if necessary).
