Migrate to SSD
Hello, I want to migrate my current OpenBSD 5.4 installation to an SSD, which is slightly larger than my present rotational drive. What are people's suggestions for doing this? I was thinking of DDing and increasing the size of /home and /usr/local, but surely there's a better way? Also, are there any /etc/fstab options recommended for SSDs? Many thanks, Laurence.

When moving to a different disk, I usually just do a basic install of the same OS version (and backup/restore software if not using something in base) on the new disk with appropriate partition sizes, then restore from backups. dd is the wrong tool for this job. Even if you didn't want to change partition sizes I think dd would be the wrong tool. Also, are there any /etc/fstab options recommended for SSDs? No need to fiddle, the defaults are fine.

Unless your installation is very specific and there is something precious beside /home and /etc/, just do a dump, install, restore. Also, are there any /etc/fstab options recommended for SSDs? None which you wouldn't use for a classical disk as well.
Re: Migrate to SSD
Check out softdep as a fstab parameter. It is equally useful for regular spinning disks but it seems like you may not know about Soft updates.
