Currently, the dependencies for the init system choice, and the
dependencies for the package, are slightly different, and not in the
same order, the latter making it difficult to assess consistency between
the two.
Fix all that, by cross-duplicating dependencies from the init choice and
the package, and order the dependencies according to the manual (arch
first, toolchain, then the others).
Note that some dependencies are redundant, but kept nonetheless for
correctness:
- BR2_USE_MMU is implied by BR2_TOOLCHAIN_USES_GLIBC, but systemd does
use fork();
- !BR2_STATIC_LIBS is also implied by BR2_TOOLCHAIN_USES_GLIBC, but it
is also inherited from kmod which we select;
- BR2_TOOLCHAIN_HAS_THREADS is also implied by BR2_TOOLCHAIN_USES_GLIBC,
but systemd does use pthread_*() functions.

Specify a space-separated list of users table locations,

that will be passed to the mkusers utility to create
|
|
users on the system, with home directory, password, etc.

See manual for details on the usage and syntax of these files.

root filesystem after the build has finished and before it is

packed into the selected filesystem images.

They are copied as-is into the rootfs, excluding files ending

help
|
|
Specify a space-separated list of scripts to be run after the
|
|
build has finished and before Buildroot starts packing the
|
|
files into selected filesystem images.
|
|
|
|
This gives users the opportunity to do board-specific
|
|
cleanups, add-ons and the like, so the generated files can be
|
|
used directly without further processing.
|
|
|
|
These scripts are called with the target directory name as
|
|
first argument. Make sure the exit code of those scripts are
|
|
0, otherwise make will stop after calling them.

config BR2_ROOTFS_POST_FAKEROOT_SCRIPT

help
|

Specify a space-separated list of scripts to be run at the end
|
|
of the fakeroot script right before the image(s) are actually
|
|
generated.
|
|
|
|
This gives users the opportunity to do customisations of the
|
|
content of the rootfs, which would otherwise require root
|
|
rights.
|
|
|
|
These scripts are called with the target directory name as
|
|
first argument. The build will fail on the first scripts that
|
|
exits with a non-zero exit code.
|
|
|
|
Note that Buildroot already provides mechanisms to customise
|
|
the content of the rootfs:
|
|
|
|
- BR2_ROOTFS_STATIC_DEVICE_TABLE
|
|
to create arbitrary entries statically in /dev
|
|
|
|
- BR2_ROOTFS_DEVICE_TABLE
|
|
to set arbitrary permissions as well as extended
|
|
attributes (such as capabilities) on files and
|
|
directories,
|
|
|
|
- BR2_ROOTFS_USERS_TABLES:
|
|
to create arbitrary users and their home directories
|
|
|
|
It is highly recommended to use those mechanisms if possible,
|
|
rather than using custom fakeroot scripts.

Specify a space-separated list of scripts to be run after
|
|
the build has finished and after Buildroot has packed the
|
|
files into selected filesystem images.
|
|
|
|
This can for example be used to call a tool building a
|
|
firmware image from different images generated by Buildroot,
|
|
or automatically extract the tarball root filesystem image
|
|
into some location exported by NFS, or any other custom
|
|
action.
|

These scripts are called with the images directory name as
|

first argument. The script is executed from the main Buildroot
|
|
source directory as the current directory.

Pass these additional arguments to each post-build or
|
|
post-image scripts.
|
|
|
|
Note that all the post-build and post-image scripts will be
|
|
passed the same set of arguments, you can not pass different
|
|
arguments to each script.
|
|
|
|
Note also, as stated in their respective help text, that the
|
|
first argument to each post-build or post-image script is the
|
|
target directory / images directory. The arguments in this
|
|
option will be passed *after* those.
