The Guided partitioning doesn't suggest any more to create /var, /tmp, /usr, etc. file systems. Is it really the recommendation to go with just / ? 2. Is there a way to use the old sysinstall to install FreeBSD 9? 3. It seems that setting up gmirror is more involved with GPT (http://blather.michaelwlucas.com/archives/1071); now I have a mirror for each of the filesystems /, /var, /tmp, etc. Is it OK to use gmirror in this way at all? 4. Also, with GPT, one has to be in single user mode to synchronize disks - correct? 3. Assuming one has enough RAM, is zfs mirror or raidz recommended over gmirror? Prior to FreeBSD 9, I used to take the the sysinstall defaults with some overrides as I thought appropriate and proceeded to set up gmirror - it was simple and not a lot of work, and a good way to make use of older systems... -- Janos Dohanics
