If there is (a lot) more push-back on this we'll reconsider it. But the AUTO setting is only appropriate for machines that are "actively being watched over". In -stable branches we start to have people using it for large data centers full of machines that are only "partially watched over" at best as well as machines stuffed in phone closets in remote locations, etc. Having the AUTO setting for situations like that can mean increased time for a reboot to happen, there is extra risk of the machine wedging and not rebooting at all (requiring manual intervention to get it back up), there is risk of disk space issues, etc. Having the default be NO and the user needing to do something to turn it on is more appropriate for those environments and helps insure that if crash dumps are being generated someone is actually interested in them. Typically this is something that's beneficial to us as you very correctly point out above but it's not necessarily beneficial to the end-users... --=20 Ken Smith - From there to here, from here to | kensmith@cse.buffalo.edu there, funny things are everywhere. | - Theodore Geisel | --=-upvYi8cf+Hhp+xMBOJcS Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iEYEABECAAYFAkqpGH8ACgkQ/G14VSmup/b7bACfYaoh+W45ZFr/liqUEr7592AQ RPkAn3EtMsxZa9bcoHsd8J3AIbIf1eTS =2aqK -----END PGP SIGNATURE----- --=-upvYi8cf+Hhp+xMBOJcS--
