# General layout of our build directory hierarchy
#
# build/config/[<subarch>/][<medium>/][<flavour>/]<leaf-config>
# build/tmp/[<subarch>/][<medium>/][<flavour>/]<build-area>
# build/dest/[<subarch>/][<medium>/][<flavour>-]<images>
#
# Items in brackets can be left out if they are superfluous.
#
# These following <image> names are conventional.
#
# For small changeable media (floppies and the like):
# - boot.img, root.img, driver.img
#
# For single bootable images (e.g. tftp boot images):
# - boot.img
#
# For compressed single bootable images (harddisk or hd emulation):
# - boot.img.gz
#
# If those are not bootable:
# - root.img.gz
#
# Raw kernel images:
# - vmlinux or vmlinuz
#
# Example:
#
# dest/
# |-- cdrom-boot.img
# |-- floppy
# |   |-- access
# |   |   |-- boot.img
# |   |   |-- drivers.img
# |   |   `-- root.img
# |   |-- boot.img
# |   |-- cd-drivers.img
# |   |-- net-drivers.img
# |   `-- root.img
# |-- hd-media-boot.img.gz
# `-- netboot
#     |-- initrd.gz
#     `-- vmlinuz
