Brian,

I think you can't change ufsdump default.
The untested attached patch might do what you want.

Is there a way to default to "yes", we gave tar-dumps a
chance but it took so long to map the file system (mailserver
with separate files for each message, not-unix format but
cyrus imap under sendmail) that the server times out waiting
before dumps actually start to transfer.
