Fix the breaking DMA port?

[Dan Mahoney (Ports)]

All,

Could we pretty please get:

a) The dma port unbroken?  (https://portsfallout.com/fallout/277280/ — but the fix seems to be here: https://github.com/corecode/dma/commit/c3a04c866881d43a71f6d005f3a5006ba83151af)

and if you’re feeling nice...

b) dma in base MFU’s (moved from upstream) to align with this?

Dayjob uses it, and there’s a couple of newalias-related bugs which our puppet install trips over.  (it runs newaliases when it modifies aliases).
