Comment(by ficus):

 Some background and references:

 "Safe upgrade of embedded systems" FOSDEM talk (2012)
 https://archive.fosdem.org/2012/schedule/event/699/130_Presentation_Safe-
 Upgrade.pdf
 Describes a bunch of strategies. Notes problems with using package-based
 upgrades.

 NanoBSD update process (manual). Have two rootfs partitions plus an extra
 configuration partition. Upgrade by writing to the "other" patition, then
 try to reboot into it; if there are problems fall back manually to the
 first partition to fix the issue.

 pfSense automates the above through the web interface:
