somewhat dependent on the naming above, if you go with silos {000..020} on
both ubuntu & ubuntu-rtm, you'll have to designate :)
otherwise it'd be implied, if i'm in silo21 i'm rtm

won't every project have an rtm branch (and a trunk) ? therefore, any MP
targeting project-rtm would be for rtm ?...although, that might take some
flexibility out of mixing rtm/ubuntu for debug/test purposes (non-landing
silo builds).
