All of them, right? The whole pls framework is gone -- replaced by plm.
There are some OB1 and openib parameters that got renamed, too
(probably in other BTLs as well -- the pipeline parameters, etc.). So
if we want to bring this functionality over, we can, but we should
then also commit to adding deprecated synonyms for all the old names.
It's not hard to do (2 function calls per deprecated name: 1) lookup
the index of the new name, 2) register a deprecated synonym for that
new name), but it does involve some menial labor.
Ralph raises a good point -- perhaps we should have a definitive
policy (that starts in v1.3) about MCA parameters. I know that Sun
has examples for this stuff. Is there one that we can implement easily?
