FreeBSD doesn't have this problem. The ports system (which builds from source) and the package system are nicely integrated. If you install sources from other than the ports system, you may have problems. However, you can create a port for that, and install it even if it's not put into the official ports tree (but do send-pr it so it can be put in the ports tree)! > 2_ There is not a simple way to make your system completly > evolving.

If you're going from an a.out system to an elf system, you'll need to do a "make ugprade" as well. > Do you really use "make world" on server, taking the risk of a > potential problem ? Some people report doing that, but I don't. On production machines, I do: make buildworld make buildkernel make installkernel reboot # to single user mode make installworld mergemaster reboot to verify that the kernel will boot before doing the make installworld. > There is a way to configure the system (using a cron job) to get via > CVS the latest release of all the software already installed (and > only the software already installed), and if there is new release to > "make install" them ? (My dream is to do that automatically, like > that I don't need to manually update the system, when there is a > urgent vulnerability, for example.) In theory, yes. In practice, I wouldn't recommend it because the mergemaster step above requires intelligent interaction. You could skip it and run it after rebooting, but that's a bit dangerous. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
