$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.
|
|
-S|--suite NAME: Override the default suite [unstable]
|
|
-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!
|
|
|
|
Overriding the default suite also configures the root filesystem to look
|
|
for updates within the specified suite.
