Playing nice with others

Well, maybe my statements were a bit too harsh. But we see it from the
mgetty side, and there's nearly nobody out there who would assume
mgetty's locking behaviour is anyhow at fault. If the other application
(just to sound as some os-vendor... ;->) doesn't work with mgetty in
*one* case, and many people do have working setups (inclding me), then I
think we can safely assume (and I guess my statements are still to
harsh...) that there's something wrong with that one setup, namely, the
ppp daemon does not perform correct locking, can't we?

So maybe we (probably we two in private) could reiterate your setup just
to find the culprit, there's always room for a discussion.

Cheers,
Klaus
