There is a config file in /etc/opkg/opkg.conf. It can be updated to set the db directory, as described in the OpenWRT Opkg documentation.

You might want to change the lists_dir ext /var/opkg-lists to lists_dir ext /path/on/disk if your device has 32 MiB
   or less of RAM and you expanded your firmware's storage space in an external drive, so you can use opkg without
   causing Out Of Memory errors.

With the migration to a versioned squashfs/overlay boot process I now have a structure on the third partition that is non-volatile and could be used for package management. It's arguable that package management should exist within the overlay, of course. So research should be done on how to handle packages on system upgrades.

The full set of config file options is available in the man-page.

Options I probably want to add:

• arch
• cache_dir
• info_dir
• lists_dir
• status_file
• tmp_dir

Some that I need to investigate:

• offline_dir
• overlay_dir
• volatile_cache

I might want to setup a dummy download url for later use too.
