It's more natural for me to use the standard update technique than redo those changes from scratch each time I update the OS. (I'm using SaltStack to configure more and more, but even getting a minion set up means it's easier to update the standard way than start with a fresh install image and have to re-bootstrap SaltStack.)

The reason I do the "crossbuild" + "rsync" thing is that it gives me the
ability to do the buildworld/buildkernel/installworld/installkernel
paradigm to a "holding directory" on a very fast machine, then rsync the
results. (Mounting the holding directory via NFS works as well but I
see no real advantage to that over using rsync)
That means I don't lose anything I did to the machine after install
(e.g. users, etc) and in addition I can put local patches on the source
tree if required, but I still get a reasonable build time.
