From what Ian said elsewhere in this thread, the O_TRUNC already does
not "act strange" on a tape device. I don't see any new POLA issues if
adding O_TRUNC to the write call doesn't change how dump(8) has been
working on tapes for FreeBSD for these n years now. The only POLA
issue I see is the current behavior that "regular" files are _not_
truncated, which was the start of the thread and the issue in the PR.

I don't see who would care if FreeBSD's dump(8) might have some funny
reactions on UNIX-like systems where O_TRUNC has a different behavior
on tape devices. I don't think the Project is overly concerned about
porting FreeBSD's dump(8) to other OSes.
