You can only do this if /usr/ports is directly after /usr. Use disklabel sd0 to get the positions. However, if /usr/ports is big enough and it's in the wrong spot, you can play games with switching them. I do this occasionally. If you can pull this off, use the n command in disklabel to rename /usr to something like /usr2 and /usr/ports as /usr/ports2, fiddle things around and then turn /usr2 into /usr/ports and /usr/ports2 into /usr. What I don't see is /usr/local and that makes things much harder unless you can pkg_delete everything and then re-install. You might find it much easier to ditch /usr/ports, add /usr/local to disklabel and another for /usr/ports that is much smaller. But we need to see your disklabel or any advice is hard to give. Also, by not having a /usr/local partition, your security is worse since that is the only partition that should use wxallowed in /etc/fstab. Basically, this is going to be really easy or really challenging. growfs works well. There is no such command as shrinkfs, but it can be done if well planned, usually. Or maybe not. Others may have different advice, but put up your disklabel sd0 here for sure. Just be glad you don't need to move /var. I've done it but ugh! Chris Bennett
