[Buildroot] Reg: Add a downloaded tar file directly to rootfs

[ravi chandran]

Hi,
     I am having a set of directories and files(actually contain some
add-on packages), which needs to be populated inside /srv directory  of
target system. I need a way to download the archived file and put it under
one of the directory of the rootfs. And during the target system
initialization, using init script i will extract the files and populate it
under the /srv directory.

     could some please provide some hint, what is the right way to do this
in buildroot?

Thanks..

You can use BR2_ROOTFS_OVERLAY or BR2_ROOTFS_POST_BUILD_SCRIPT or a 
combination of both. See the detail on these and other local customizations in 
chapter 9 "Project-specific customization" of the Buildroot manual:

BR2_ROOTFS_OVERLAY points to a directory tree that is copied over the rootfs. 
To fetch a tar file from somewhere you can use BR2_ROOTFS_POST_BUILD_SCRIPT, 
and extract it in $TARGET_DIR. See the details in the manual:
