Live Upgrade
So after years of just jumpstarting my machine on my way out of the office when a new build comes out I decided to bite the bullet and play around with Live Upgrade. So what is Live Upgrade I hear you ask, to put it simply its a method of upgrading your system while your system is still running, and as such minimising downtime.
Basically make sure you have a partition/disk available thats the same size as your root disk, and as root call /usr/sbin/lu and follow the menu options to first create and then upgrade an alternative boot partition. Finally you just activate the boot env and [updated] init 6 [/update] (don't use reboot, the new partition won't be picked up).
Of course all of this can be scripted as well, next experiment ;).
