Picking a semi-random message to reply to, I seem to recall Solaris
has a separate /devices filesystem for this: all entries are dynamic,
so the filesystem is strictly readonly from a userland point of view.
In our case, we would have quite a lot of overlap with devinfo, but it
could still be something to keep in mind.
