So the question is back to the beginning: I installed 9.1-RELEASE, then binary upgraded to 9.2-RELEASE using freebsd-update.  Now all files I checked are correctly in 9.2-RELEASE-p4.  For example:

1. the kernel contains the new version:
 
# strings /boot/kernel/kernel | grep RELEASE|grep 9
@(#)FreeBSD 9.2-RELEASE-p4 #0: Tue Apr  8 18:08:22 UTC 2014
FreeBSD 9.2-RELEASE-p4 #0: Tue Apr  8 18:08:22 UTC 2014
9.2-RELEASE-p4

2. /etc/hosts contains 9.2:

# $FreeBSD: release/9.2.0/etc/hosts 109997 2003-01-28 21:29:23Z dbaker $

We have verified that:

1. I never compiled kernel, and do not have /usr/src and /usr/obj folders now.

2. the default /etc/profile is unchanged, in particular I never defined UNAME_* vars .

3. I also tried "unsetenv UNAME_r"

However, uname somehow shows the wrong version 9.1:

# uname -a
FreeBSD localhost.localdomain 9.1-RELEASE FreeBSD 9.1-RELEASE #0 r243825: Tue Dec  4 09:23:10 UTC 2012     root at farrell.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  amd64

So where does uname get the version number from?  Which file(s) might not have been upgraded?  Thank you!
