RC3 uses tar-1.14-10 while RC2 used tar-1.14-9 so the newer build is a lot more verbose than before. I've dropped back to the earlier version for sanity sake.
tar-1.14-10 is a security update from redhat (fixes a security vulnerabilty).
Not sure if you want to revert.....
It is EXTREMELY unlikely that the developers will want to regress a security patch.
Please remember that smeserver is based on Centos 4 (which is based on RedHat ES4), and that tar is part of the base Centos install, so you need to look for information/fixes at RedHat.
