True, but that has absolutely nothing to do with how hard and/or easy it is to build and/or install a new kernel, or how hard and/or easy it is to back out of such an action if it goes wrong. I've as yet to run into a Unix system where the latter was really hard, though AIX made a good attempt at that. Other operating systems tend to be more difficult, depending on the OS. We typically dealt with that by keeping the system on one pack, and the users data on another, so backing out a broken install meant putting the old OS pack back in. > > As far as I can tell, it's easier to back out > > of failed kernel install on Unix than it is to > > back out a failed application install on > > Windows. > That is also my impression, based on my first attempt to build a custom kernel > yesterday. In which case, needing to build a new kernel to enable SMP on FreeBSD should bother you less than needing to install Office to get a word processor on Windows :-). http://www.mired.org/home/mwm/ Q: How do you make the gods laugh?
