(cherry picked from commit 5cf5dce05a)
./packages folder
Add .ipk packages to this folder will allow the ImageBuilder to install them.
For more complex setups consider adding a custom feed containing packages.
src custom file:///path/to/packages
Whenever the ImageBuilder builds a firmware image this folder will be reloaded
and a new package index created. In case signature checks are enabled the
./packages/Packages index will be signed with a locally generated key pair.
