I dont want to use the standard upgrade method because a)I have read a few people have had problems with the 2.1.7 upgrade taking serveral tries before working. This is a production machine that I cant have down for an "unknown" length of time with reboots and potentially tape backup restores b)Although its a production machine, I would sort of like to use it as a general test to upgrading our main server. Also, if I can compile with optimizations, and I can get a bit of a performance boost out of it then great. Its a pentium and the -m486 and -HAVE_FPU should in theory help for some of our apps... There is at least one user who runs some FP transformations on occasion. I have tried this method on my home machine, and it 'seemd' to work. However, its the first time I did a make world, and I couldnt find much documentation on it... Any idea where I can find more docs on the process ? Again, the procedure I followed was 1) Slurp down the src from ftp.freebsd.org in FreeBSD-stable/src 2) moved my old /usr/src to /usr/src.old and untared the stable src to /usr/src 3) did a make world in /usr/src 4) did a make install 5) went to /usr/src/sys/i386/conf and did a config, and recompiled and make install 6) did a reboot and all "seems" fine... But I am worried I missing anything here... I guess also, I would like to move to CSV style updates... Apart from the man pages, are there any extra docs on it?
