Provisioning a remote package server

Setting up an HTTP remote package server and pointing your target clients at it is easier than you might think. The client-side server address configuration varies between package managers. We will configure opkg manually on the Raspberry Pi 4.

Let's start with the package server:

1. First, navigate one level above the directory where you cloned Yocto.
2. Next, set up your BitBake work environment:

   $ source poky/oe-init-build-env build-rpi

   This sets a bunch of environment variables and puts you back in the
   build-rpi directory.

3. Build the curl package:

   $ bitbake curl

4. Populate the package index:

   $ bitbake package-index

5. Locate the package installer files:

   $ ls tmp-glibc/deploy/ipk

   There should be three directories named aarch64, all, and raspberrypi4_64 in ipk. The architecture directory is aarch64, while the machine directory is raspberrypi4_64. The names of these two directories will vary, depending on how your image has been configured...
