There was a thread about it last october. I c&p part of my answer here:

--
>From uname and uname(3) man pages,

"An environment variable composed of the string UNAME_ followed by any
 flag to the uname utility (except for -a) will allow the corresponding
 data to be set to the contents of the environment variable."

The -a flag behave as though the options -m, -n, -r, -s, and -v were specified. Freebsd-update can modify /root/.profile or better, /etc/profile, adding those environment variables with correct and update values.
