XFCE installs and boots correctly.
The mouse cursor not working?
Can still open the Run dialog with Alt+F2 to start a terminal however.
DNS+networking seems okay.
Can 'apt-get update' but the security suite wasn't enabled by default - it's commented out in /etc/apt/sources.list - that's OK since kfreebsd wheezy didn't any repository for security updates.
During upgrade process to jessie-kfreebsd, user is asked: disable passworded root logs via SSH; restart services automatically...
XFCE terminal crashed during the apt-get dist-upgrade!
Tips for upgrading to jessie-kfreebsd:
update by hand /etc/apt/sources.list "wheezy" -> "jessie-kfreebsd"
also add jessie-kfreebsd-proposed-updates
make sure the security.debian.org line is there and uncommented
apt-get update && apt-get upgrade
make sure kfreebsd-10.something is installed in /boot/
