Changing the represented release name is not a generally wise idea. You
may also want to modify sys/sys/param.h, consult the FreeBSD Porters'
Handbook for more details.
If you just want to cheat uname(1) and/or sysctl(8), perhaps renaming
them to _uname and _sysctl and use some sort of _uname $@ | sed -e
s/`_uname -r`/6.1-RELEASE/g trick will do. This also applies to the
rc.d motd script, which uses uname(1) to determine the current FreeBSD
version. This trick is less intrusive, but have no effect if your
application read the version themselves, e.g. the build process of
