uname gets its info from the kernel so even in a jail you get the kernel
version unless you've used the jail setup parms to override the version
reported within the jail (a feature that's only available on -current
right now).

You can use 'uname -U' to report on the version number that was in
in /usr/include/osreldate.h when uname was compiled, which is about the
closest you can get to "what version is this userland" I think.  (I
guess you can also look in /usr/include/osreldate.h within the jail.)
