I am currently running 3 freebsd boxes sharing tasks for the same domain: 192.168.0.1 web.server.com web 192.168.0.2 sql.server.com sql 192.168.0.3 mail.server.com mail Problem is: how can I avoid having to build/install world and, to a lesser extent, the kernel for each machine (same hardware)? Solution 1: netbooting I have already encountered the problem of compiling the kernel in aout format instead of the default elf format on 3.x in order to be able to netboot the kernel. Once that will be settled, one of the three machines will act as the boot server for the other two. These machines will then mount only need the local hdd to mount swap and the following directories: /etc, /tmp, /var, /usr/local. Problem is: even though my objective is reached and only one build/install will be necessary, how much compromise in performance or potential problems can I expect from such a setup? Solution 2: mounting directories from fstab If possible, this option would mount the directories installed during "make installworld". This will prevent me from having to build/install world on each machine, but I'll still have to install a kernel for each machine. Problem is: how do I know which directories must be mounted in order to avoid having to build/install world on each machine? Also, can I expect any compromise in performance or potential problems for this kind of setup also?
