Would definitely like to see this, with a recent install on a Wandboard Dual with a USB2 sata disk for the rootfs. It installed fine with jessie's debian-installer, but failed on initial boot. I worked around it by adding to /etc/initramfs-tools/modules: ci_hdrc_imx phy_mxs_usb I haven't yet verified if only adding "phy_mxs_usb" instead of both will work. Had a similar problem with an Odroid-XU4 install (which isn't yet supported by debian-installer), and worked around it similarly, although haven't narrowed down exactly which modules are needed, though I suspect one or both of: phy_exynos_usb2 phy_exynos5_usbdrd Something that pulls in all the phy-* modules would likely fix the issue in a generic way, rather than playing whack-a-mole with various phy types. live well, vagrant
