Is that true? I thought it was just the CST that was extensively tested; that's
only released quarterly, whereas RSUs are released every month.
IBM's RSU (Recommended Service Update) is assigned like this:
IBM's monthly RSUs (RSUyy01, 02, 04, 05, 07, ...) identify PTFs that fix
HIPER, PE, Security/Integrity, or pervasive problems *AND* have
completed a 30 day CST (Consolidated Service Test) cycle.
IBM's quarterly RSUs (RSUyy03, 06, 09, 12) identify the usual monthly
RSU PTFs as described above, plus all other PTFs that have completed at
least a 90 day CST cycle.

Chuck Norris never uses CHECK when he applies PTFs.
