To clarify, you sometimes can't build a new kernel with an old userland. The kernel build depends on the current userland build tools. Once you get it build, installing a new kernel with an old userland may cause things to break, with the likelyhood and amount of breakage both increasing as the time difference between them increases. For the record, going the other way - an old kernel on a new userland - is worse, as kernels are generally expect to support old features, but can't support features that didn't exist when they were built. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Q: How do you make the gods laugh?
