Not as straightforward as on FreeBSD, but you can make your own read only NetBSD device quite easily. I've been doing it for years, and it works perfectly.

@stefano@mastodon.bsd.cafe yap, Excellent article; I used it to build a reliable read-only router😀 mfs itself isn't actually used, though - tmpfs is used instead 😉

@stefano@mastodon.bsd.cafe Is it secure enough to be used for analyzing unknown USB keys or the like ? That is, is there actually no way for an attacker to bypass the read-only setting ?
