I have some questions regarding the new boot blocks used in FreeBSD 3.1: (1) Can these boot blocks (I assume that they can occupy at most 15 sectors because we need one sector for the disklabel in the first 16 sectors. BBSIZE == 8192) reside in a filesystem other than the root file system? (2) Is the boot block code smart enough to find the kernel or loader (/boot/loader) in a different FreeBSD slice (Suppose we have more than one FreeBSD slice on the same machine and the root filesystem happens to be on a different slice. I believe that the slice where the boot block code is used must be set to be active). (3) It seems to me that the loader (/boot/loader) can set up some kernerl configuration parameters (e.g. nmbcluster) that override what you have in the kernel. Can anyone describe a little for me on how this is achieved? Any help is appreciated. -------------------------------------------------- Zhihui Zhang.
