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? I've done variations of both, netbooting and nfs mounting key directories, and while its a great solution for end-user type workstations, non-critical servers or identical server farms, I've found that by focusing my points of failure to one machine I increase my troubles, not decrease them when dealing with critical services. Even if you have a rock-solid NFS setup, what happens when a make installworld screws up? Do you want to lose all the machines, or just one of them?
