Customizing the generated target filesystem
|
||
|
|
-------------------------------------------
|
||
|
|
|
||
|
|
There are a few ways to customize the resulting target filesystem:
|
||
|
|
|
||
|
|
* Customize the target filesystem directly and rebuild the image. The
|
||
|
|
target filesystem is available under +output/target/+. You can
|
||
|
|
simply make your changes here and run make afterwards - this will
|
||
|
|
rebuild the target filesystem image. This method allows you to do
|
||
|
|
anything to the target filesystem, but if you decide to completely
|
||
|
|
rebuild your toolchain and tools, these changes will be lost.
|
||
|
|
|
||
|
|
* Create your own 'target skeleton'. You can start with the default
|
||
|
|
skeleton available under +fs/skeleton+ and then customize it to suit
|
||
|
|
your needs. The +BR2_ROOTFS_SKELETON_CUSTOM+ and
|
||
|
|
+BR2_ROOTFS_SKELETON_CUSTOM_PATH+ will allow you to specify the
|
||
|
|
location of your custom skeleton. At build time, the contents of the
|
||
|
|
skeleton are copied to output/target before any package
|
||
|
|
installation.
|
||
|
|
|
||
|
|
* In the Buildroot configuration, you can specify the path to a
|
||
|
|
post-build script, that gets called 'after' Buildroot builds all the
|
||
|
|
selected software, but 'before' the rootfs packages are
|
||
|
|
assembled. The destination root filesystem folder is given as the
|
||
|
|
first argument to this script, and this script can then be used to
|
||
|
|
copy programs, static data or any other needed file to your target
|
||
|
|
filesystem. You should, however, use this feature with care.
|
||
|
|
Whenever you find that a certain package generates wrong or unneeded
|
||
|
|
files, you should fix that package rather than work around it with a
|
||
|
|
post-build cleanup script.
|
||
|
|
|
||
|
|
* A special package, 'customize', stored in +package/customize+ can be
|
||
|
|
used. You can put all the files that you want to see in the final
|
||
|
|
target root filesystem in +package/customize/source+, and then
|
||
|
|
enable this special package in the configuration system.
