$PROG - cross-built chroot Emdebian rootfs builder
version $OURVERSION
Syntax: sudo $PROG [OPTIONS] [COMMAND]
Commands:
-?|-h|--help|--version: print this help message and exit
--create|create: create a cross-built base tarball for ARCH
Options:
-a|--arch: Override the default cross-build architecture (from dpkg-cross).
-s|--script FILENAME: Override the default package set and second-stage install.
-m|--machine NAME: Specify a machine name for customisation hooks
-v|--variant NAME: Specify a machine variant name for customisation hooks
--machine-path PATH: Specify a path to replace the $WORK/machine default
Although based on debootstrap, $PROG cannot support the full range of
debootstrap commands or options.
Some customised $PROG scripts are provided with emdebian-tools. The
default uses the standard Emdebian 'busybox' package with 'dpkg' and 'apt'.
Replacement scripts need to be full debootstrap suite shell scripts that specify
how to complete the first and second stage installations. If the script uses
'busybox', the second-stage install function must be compatible with the
shell applet in busybox - avoid bashisms!
