On amd64, we use grub instead of U-Boot, because yours truly can't
figure out how to handle ACPI handover to the kernel.
The resulting image is now called disk.img instead of the old mmc.img,
since we can use it over any interface (e.g. virtio or SCSI).
In the new model, we have three sources of storage:
- /mnt/var: Mountpoint for a disk with the label "var"
- /mnt/cfg: Mountpoint for a disk with the label "cfg"
- /mnt/tmp: Mountpoint for a ramdisk
These sources are used for the following overlays:
- **/cfg, /home, /root**: /mnt/cfg if available, else /mnt/tmp
- **/etc**: /mnt/cfg if available and the boot/etc finit condition is
set, else /mnt/tmp
- **/var**: /mnt/var if available, else /mnt/tmp
- **/var/lib**: /mnt/var if available, else /mnt/cfg if available,
else /mnt/tmp
See board/common/rootfs/lib/infix/mnt for more information.
The virtualized system is configured through kconfig under "External
Options"->"QEMU Virtualization".
To launch the system, simply run "make run". This works both from
output directories, and from the infix root with O= set.
