Would we, then, also get /dev/pts/<number> for name <-> pty mapping?
That's one of the few things I like better about Linux than BSD...
There are only so many /dev/ttyXY's you can use, and it looks quite
obnoxious in 'w' or 'who' compared to Linux, where you just see
'pts/whatever'. Of course, I don't claim to know what the official
stance on any of this is, so I'm just tossing out an opinion.
