Why not make an iso image that has the installer/install image. This
can be booted from a partition. (you can use isohybrid --partok to
patch the iso image to make this possible). My install script that
gets run off from the iso image runs an extlinux update on the on the
target partition after the new filesystem image is copied to the
target.

I do remote installs that way, but your situation may be a bit different.

Booting an iso image that has the squashfs image eliminates the need
for all that.
Just a suggestion, I don't know exactly how your upgrade process actually works.
