You need to be sure to use the bsd.rd from the snapshot! You say install, which is very different from upgrade. Even with a fresh install, if you want to keep something like the existing /home directory, just don't include it in the new disklabel. But be sure to be able to correctly include the correct mount directories for the existing partitions which will come up if you pick a custom disklabel. For example typing 'n a' will let you enter / as the partition mount point. I wouldn't try upgrading if you want a snapshot since so much changes. Note that you can put the files on the directory that you don't want to get newfs to run on, but be sure NOT to add it in the disklabel until you are done with the install. Also, using ! will get you into the shell if you get confused. I recommend backing up the partition you want to keep, /etc and the list of packages you will need to re-install. Sometimes packages you were using have been dropped, so be prepared to deal with that. If you have another USB, install the OS and play around with it until you get a good idea of what's going on. It's kind of cool once you see all the tricks you can do. Just be sure to play around after you have OpenBSD installed so that you will find that the original disklabel shows up during an install under the custom option, just without the mount points showing up. Also, watch where the mount points start and end. You can growfs a partition if and only if you are using the partition that follows it. Which means that you should add partitions in the order that let's you sacrifice the next one if you find something like /usr/local too small. /usr/local followed by /var would be a bad idea since messing with /var is possible but a real pain to do. Have some fun. umount a partition that isn't essential and run fsck, not fsck -fp on it and see what gets done. Enjoy! Chris Bennett
