8# End result is two things:
9#
10# 1. A .hddimg file which is an msdos filesystem containing syslinux, a kernel,
11# an initrd and a rootfs image. These can be written to harddisks directly and
12# also booted on USB flash disks (write them there with dd).
13#
14# 2. A CD .iso image
15
16# Boot process is that the initrd will boot and process which label was selected
17# in syslinux. Actions based on the label are then performed (e.g. installing to
18# an hdd)
19
20# External variables (also used by syslinux.bbclass)
