Upgrade from FreeBSD-11.1 to 11.2 (released two weeks ago) on
trey.marshlabs.gaertner.de, a lenovo X220
ThinkPad.
(Time needed to do the update: 1 hour with the fast Internet connection in the office and the SSD in the laptop. Beyond the commands
freebsd-update upgrade -r 11.2-RELEASE
freebsd-update install
shutdown -r now
freebsd-update install
no manual interaction (e.g., for merging /etc
config files) was needed. Everything went smoothly.
Initial testing looks OK. Next week, I should do the same upgrade on my desktop system in the office.
