I think you are exaggerating a bit about the reliability of 2.7.2. Look, I'm not defending Linux here against FreeBSD. I switched a few weeks ago and I'm very happy with it. Using FreeBSD saves me a lot of time and gives me a system that is much easier to administer. But Linux also is quite a lot of source code where a lot can go wrong, if you put everything together. Comparable in amount and complexity to /usr/src of FreeBSD. I had my own "distribution" that was completely compiled with 2.7.2 (plus some patches made by H.J. Lu) and -O2. There were no problems (especially not the last months after H.J. Lu's latest patches) caused by compiler bugs. Who says 2.6.3 is bug free? There is always a small chance for compiler bugs. In those rare cases a workaround may be needed. I doubt that the latest release of 2.7.2 (2.7.2.9) has more bugs than 2.6.3 had. -- ______________________________________________________________________ Peter Mutsaers | Abcoude (Utrecht), | "Quod licet bovis, plm@simplex.nl | the Netherlands | non licet Jovi."
