If I rembember correctly, the 512MB number was somewhere in the "possible but not comfortable" range way back when the text was originally written. But that was before several space consuming things such as the relinking at boot steps happened. A more realistic estimate looking a the various systems I have within reach suggests "you can squeeze in a full install inside 1GB, but if you plan on installing any packages or storing data locally, there is no point in setting yourself up for the pain of running out of storage". You could probably find the absolute minimim (an actually quite useless number) by checking the uncompressed sizes of the *.tgz install sets, but the last time I remember doing a "df -h" on a fresh install before installing any packages or introducing any data, the total ran to somewhere in excess of 650MB. The system with the least storage allocated that I interact with regularly is a thing that runs spamd and some content filtering, with a total of 6GB storage, and at most times uses about two thirds of that. If the bare minimum size for an OpenBSD install is vital information to you for some reason, the way to find out is to do a fresh install using only the Enter key, then recording he total used after first reboot. The exact number is likely a little different across the 14 supported architectures. -- Peter N. M.
