It does not have to be that way. Use only one disk for the system and the second disk for a poudriere ZFS pool ? > I have / for > all.the system and /usr/local for poudriere on the 2nd disk. Use the same setup, but with ZFS. I think, but have not checked it, that poudriere uses zfs clones, which is ***way*** more efficient than copying the whole tree for each poudriere builder jail. > > SSD instead of spinning disks ? > No. Seagate SAS disks. 3.5" or 2.5" ? Putting the poudriere storage on a SSD might be very helpful.
