--- Comment #1 from Florian Weimer <fw at deneb dot enyo.de> ---
Matching on ut_line leads to unbounded utmp file growth, so I don't think
that's an option.
OpenSSH could use a different encoding for the PTY name, perhaps base64. 24
bits for the PTY name should be enough.
The utmp family of interfaces is really only suitable for systems that can
support just a fixed number of terminals, so there is no good fix here. Maybe
PTY usage should not be logged via utmp at all.
