Trond suggest to delete them before rebuilding, so they get updated too, nice suggestion. Mine sets different information in UNAME_* and vers{ion,.c} files. This discrepancy should be avoided.

Thanks. I don't have the folder /usr/obj/usr/src/sys/ . Under /usr/obj/usr/src/ I only see two folders: lib32 and tmp.
I did find a file /usr/obj/lib32/usr/src/include/vers.c , that contains the incorrect version:
#define SCCSSTR "@(#)FreeBSD 9.1-RELEASE #0: Mon Jan 21 15:45:14 UTC 2013"
#define VERSTR "FreeBSD 9.1-RELEASE #0: Mon Jan 21 15:45:14 UTC 2013\n root@:/usr/obj/lib32/usr/src/include\n"
#define RELSTR "9.1-RELEASE"
That's closer now! However, I never compiled the kernel, I only installed 9.0-RELEASE and ran freebsd-update to upgrade to 9.2-RELEASE, so don't know how these /usr/obj files were produced. I installed virtualbox before, maybe that produced /usr/obj ?
Anyway, I have deleted these folders /usr/src/ and /usr/obj/ , then ran svn to install /usr/src/ , and then rebooted. Yet "uname -a" still says the incorrect 9.1-RELEASE. Now I don't even have /usr/obj , where does uname get that incorrect version now?
