I'll see what I can do.

So far I've implemented ptsname(3). Patch in:

Please review & comment.

Am working on this, and would welcome suggestions/feedback/testing.
My branch 'devfs'[1] on leaf contains the patchset.
One of the commits relates to switch openpty to use unix98 ptys. This is kinda
experimental so you might choose not to try that. Am about to try it myself.
