I believe the goal of quiessing the devices (someone please correct me if
I'm wrong) is so that data is not changing while ufsdump is doing it's
job.

Well, data only changes if you write to it. Thus would write-locking the
device(s) in question be sufficient? Reads shouldnt interfere (and atime
updates are prevented when write-locking is turned on). This strikes me as
a less intrusive approach to solving the "everybody be
still!" requirements of ufsdump.
