Btw which ports wi= ll=20 > break? >=20 I did not keep a list, but as far as I remember, the 'pure-pw' binary from pure-ftpd was the last thing that failed. Because it was not visible in first place (the port builded fine), I decided the risk of breaking things without noticing it was not worth it. I don't mean that it's a bad thing, but it will cost you some time to find the bugs, report the bugs and get them fixed. And if you are willing to use it in a production environment, you have to fully test the software eacht time you are upgrading to be sure things will not break. It's also not officially supported as far as I know. Kind regards, Jimmy Scott --=20 People usually get what's coming to them ... unless it's been mailed. --lrZ03NoBR/3+SXJZ Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (OpenBSD) iD8DBQFDYTFygDLTDEgDPT0RAlh4AJ0ccvAUXpHciDwEM8UEe9fMq8CAPQCeK+lE ExjtwwBMk2F/bkM0iD7HA3E= =6oQq -----END PGP SIGNATURE----- --lrZ03NoBR/3+SXJZ--
