I am using the squashfs/overlay image for espressobin on a large SD card. Currently in order to use the entire card some manual steps and card-shuffling are required. Could this be done automatically at boot-time before the overlay partition is mounted?
I'm lost...maybe I should ask to be sure...
Are you aware that you only need to perform the step once?
I'm not sure how the online drive can re-partition itself....unless you meant something else?

Yes, per image. I'd like to be able to update with the latest image builds on a regular basis, ideally with a minimum of manual steps. Maybe the standard is to just update in the overlay FS via opkg? How does one do a system upgrade that way?
OK! Cool! I understand now.
You may be able to build this as a custom image.
You cannot update the whole image via package updating.
You should never update packages, it might break things.

Other SD-based distros do it, i believe with the root partition mounted: https://github.com/armbian/build/blob/master/packages/bsp/common/usr/lib/armbian/armbian-resize-filesystem
