- Bret is correct. SAM executes "/system/TOOL/get_kdfile /hp-ux" to retrieve
- the dfile used to build the kernel and then parses. The method described
- in the base note modified conf.c without also modifying the image of the
- dfile found near the end of that file.
-
- As for whether SAM retrieves the correct values for kernel parameters,
- it retrieves the values used to build the kernel (unless the kernel was
- built using the proceedure listed in the basenote). The values
- returned by monitor are accurate for tunables that are static and do not
- change as time goes by. Some parameter settings are special values that
- mean "use the best value". SAM might display something like "0" or "-1"
- and monitor would show the current value as the kernel has set.
