The tweaks needed were to redefine or change the 'link' and 'unlink'
functions in qmail's maildirdeliver and pine's maildir patch with 'rename'
and 'remove' respectively. 

The only reason for using hardlinks for mail delivery, afaik, is to make
storage on nfs reliable. But since we're using coda, we can move and
delete the files directly.

The other tweak needed for pine was to change the references to ctime,
because for some reason coda just leaves them set at 0 (1969!)

Unless thats a bug in an old kernel coda driver that I'm using. Also I was
happy to see that the 'mutt' mailer worked just fine out of the box,
dealing with the coda no problem -- just had to deliver the mail to the
partition with a modified maildirdeliver first.
