Make your own read-only device with NetBSD

For certain use cases, it's advisable to set up a read-only root file system, which ensures better reliability in case of system issues. Think of scenarios like a router (critical for network access) or a caching reverse-proxy, such as the one described in my seriesMake your own CDN.

WhileFreeBSD natively supports this configurationand some Linux distributions offer custom solutions (e.g.,Alpine Linux),NetBSDstands out as an excellent choice for such devices. It supports nearly all embedded devices, is lightweight, and its stability minimizes the need for frequent updates.

Exactly what it says on the tin. Friend of the website (a new term I just made up and will use from here on out for some people) Stefano Marinelli, fresh from his series about making your own CDN using the various BSDs, explains how to set up a NetBSD system with a read-only root filesystem for the special use cases where this makes sense.
