Which file(s) might not have been upgraded? Thank you! I found the source code of uname at http://svnweb.freebsd.org/base/release/9.2.0/usr.bin/uname/uname.c?revision=255898&view=markup it appears that "uname -v" does get version number from the environment variable "UNAME_v". However it's beyond me to find out where there variables are obtained - on a stock RELEASE system without /usr/src and /usr/obj.
