Me too ... But downloading latest ezjail-admin code from cvs:

     885     # Make the host systems os version our target version
     886     # Users can override this by setting the UNAME_r 
environment variable
     887     ezjail_osversion_target="`uname -r`"
     889     # Finally run freebsd-update to upgrade our basejail
     890     env UNAME_r="${ezjail_osversion_source}" freebsd-update -b 
${ezjail_jailbase} -r ${ezjail_osversion_target} upgrade install

  If I am not wrong, it is possible to do a full upgrade between 
releases, right??

  ezjail-admin cvs's version is 1.269:
