: Dear Linus,
: I thought I would forward a piece of mail to you from one of the NTP : developers. Linux has fallen from grace in their eyes (which you : perhaps already know). They are actively suggesting that people who : need to use time synchronization (NTP) switch to using freebsd.
: The cited problems with Linux are that the published interfaces to the : kernel (adjtimex and friends) change too frequently to be supportable. : (The recent /proc/pci discussion is tangential but worth noting.) The : slews of bug reports received by them are almost invariably about the : Linux platform; other platforms do not seem to suffer. I've been : actively testing the recent NTP implementations (ntp 4.0 series), trying : to report bugs as seen under Linux 2.0, but enthusiasm for fixing the : bugs on their end is all but nil.

Since I use NTP on my machines, I will do whatever I can to make sure it works properly on Linux. We have ways to deal with adjtimex in glibc 2. But I don't think it will work for libc 5. Please make sure you are running a glibc 2 based system. If you still have problems, please send me a note at hjl@lucon.org. BTW, where can I find ntp 4.0?
Thanks.
