Might it be possible to finesse the already existing envars (BLOCK_SIZE, DF_BLOCK_SIZE, etc.) to accomplish the desired suffixing mods? Or perhaps even a new envar(s) dedicated to simply specifying the suffixing, and defaulting to present behavior for backcompat...? Haven't thought this thru, just tossing it out as a possibility to think on. Might be cleaner in some respects than trying to wedge it into the options.
