What programs need it?

Doesn't the devpts filesystem mean that it's not required anymore?  I
thought devpts set up the permissions on the newly created PTY slave
devices correctly, but I could be mistaken.

Maybe programs that have statically pulled in a grantpt() function from
a system without devpts don't work, but I would think that glibc would
do the devpts detection at runtime anyway.

Actually, from the grantpt manpage:

Now I suppose the manpage may not be accurate, I don't know.
