Currently, one may only specify one list of arguments that are passed to several scripts (BR2_ROOTFS_PRE_BUILD_SCRIPT, BR2_ROOTFS_POST_BUILD_SCRIPT, BR2_ROOTFS_POST_FAKEROOT_SCRIPT and BR2_ROOTFS_POST_IMAGE_SCRIPT_ARGS). So one has to be careful that the arguments for these scripts do noti collide. To allow specifiying dedicated arguments to each type of scripts, new config options are introduced. For backward compatibility the value of BR2_ROOTFS_POST_SCRIPT_ARGS is still passed to the scripts. But now one can add specific arguments from the new config option.

#

|
# Macro that builds the needed Makefile target to create a root
|
|
# filesystem image.
|
|
#
|
|
# The following variable must be defined before calling this macro
|
|
#
|
|
# ROOTFS_$(FSTYPE)_CMD, the command that generates the root
|
|
# filesystem image. A single command is allowed. The filename of the
|
|
# filesystem image that it must generate is $$@.
|
|
#
|
|
# The following variables can optionaly be defined
|
|
#
|
|
# ROOTFS_$(FSTYPE)_DEPENDENCIES, the list of dependencies needed to
|
|
# build the root filesystem (usually host tools)
|
|
#
|
|
# ROOTFS_$(FSTYPE)_PRE_GEN_HOOKS, a list of hooks to call before
|
|
# generating the filesystem image
|
|
#
|
|
# ROOTFS_$(FSTYPE)_POST_GEN_HOOKS, a list of hooks to call after
|
|
# generating the filesystem image
|
|
#
|
|
# In terms of configuration option, this macro assumes that the
|
|
# BR2_TARGET_ROOTFS_$(FSTYPE) config option allows to enable/disable
|
|
# the generation of a filesystem image of a particular type. If
|
|
# the configuration options BR2_TARGET_ROOTFS_$(FSTYPE)_GZIP,
|
|
# BR2_TARGET_ROOTFS_$(FSTYPE)_BZIP2 or
|
|
# BR2_TARGET_ROOTFS_$(FSTYPE)_LZMA exist and are enabled, then the
|
|
# macro will automatically generate a compressed filesystem image.
