I don't know how the boot process of the RasPi works, but if it allows for booting alternative kernels/initrds, I would strongly suggest adding two bootable environments. Either as two separate partitions, or, if you're using kernel + initrd + squashfs(or nfs), two subdirectories under your boot folder. That way, you can push/pull updates of the base operating system from the running system to the non-running system in the other folder/partition and simply switch the default boot entry once the update has been completed.
I'm currently using such a code for some older non-PXE-bootable* Intel-based computers at home, but it's not ready for inclusion into X2Go yet.

*It's usually possible to PXE-boot an Intel-based computer using the images from http://boot.ipxe.org, even when the network card doesn't support PXE natively, but in my particular case, that doesn't help, either.
