[Buildroot] Adding local file system overlay

[Lars Dunemark]

Hi Buildroot mailinglist!

During development of a new platform I sometimes find it useful to bundle my test builds with my own script/configuration files. 
Example: SSH keys

This is not something that we want to include in default configuration for a board or by any way get in a final build so instead I added a second step to local file system overlay checking a local variable and if it is set us it as a roofs overlay.

Is this something that is of interests for the upstream project?

Example: 
export  LOCAL_ROOTFS_OVERLAY=/local-rootfs-overlay
make

Best regards,
Lars Dunemark

doesn't buildroot already do that ?

system configuration => overlay directory

or is your patch doing something different

on a semi-related note, I run the following post-build script for 
ssh keys :

#!/bin/sh
mkdir -p $1/root/.ssh/
chmod 0700 $1/root/.ssh/
chmod 0700 $1/root
cp -p ~/.ssh/id_rsa.pub $1/root/.ssh/authorized_keys
chmod 0600 $1/root/.ssh/authorized_keys


that will copy my public key as an authorized key on the built system

Currect Buildroot has this functionality but this requires me to update the configuration for my build target.

My suggestion is to allow this without configuration changes, making it possible to alternate a build on your local machine without risking getting it in the default configuration for that target when doing make savedefconfig.

  You can always override any configuration option on the command line:

make BR2_ROOTFS_OVERLAY=...
