[dm-devel] device mapper target vs personality, how do you decide to pick one or the other?

having stared at the code associated with these 2 constructs for a while, i cant come up with a clear reason why one would choose one over the other.

having said that, it seems that the personality code is ancestral and is used for the personalities that can be compiled into device mapper and the target code is for newer stuff that is not expected to be compiled into device mapper.

so, based on this speculation, i *think* i should be using the target construct for the new device mapper module that i am currently coding.

am i correct?
