And the reason is, you are doing something the default partition plan wasn't planning on you doing -- having a /usr/ports directory full of stuff. > $ df -h > Filesystem Size Used Avail Capacity Mounted on > /dev/sd0a 1005M 61.1M 893M 6% / > /dev/sd0k 98.8G 3.2G 90.6G 3% /home > /dev/sd0d 3.9G 724M 3.0G 19% /tmp > /dev/sd0f 2.0G 2.0G -91.1M 105% /usr > /dev/sd0g 1005M 177M 778M 19% /usr/X11R6 > /dev/sd0h 9.8G 1.0G 8.3G 11% /usr/local > /dev/sd0j 2.0G 850K 1.9G 0% /usr/obj > /dev/sd0i 2.0G 861M 1.0G 45% /usr/src > /dev/sd0e 18.3G 12.0M 17.3G 0% /var > > I want to reinstall OpenBSD from a snapshot and pick a custom partition > scheme.

First of all, all Ingo's suggestions are right on. But I'm going to do something I rarely do: give a short answer. :) You don't even have to reload. Save your existing /home partition, and shrink it to maybe 20g, then restore it. Now you have lots of space to create a new /usr/ports, or whatever else you may need in the future. As for root being "only" 1G, actually, I'd call that kinda big. I've run systems for many years with 200MB root. There just shouldn't be much going there, and if there is, it usually indicates something has gone wrong, so an early warning is nice. (/dev is in /, so a common error is to end up trying to write to a device, but mistyping it and making a file there instead). /var ... "depends". If all you have is routine logs going there, than 1G is "big". If you have an app that has a database or a web app, suddenly your 18g may look small. What are you developing? Web apps? /var (holding /var/www) will suddenly be small. Guess I lied about the short answer... :-/ Nick.
