* cannot yet implement <utmpx.h>, because our on-disk file format lacks

* want to allow logging of user login records generated by unprivileged
* processes as well, provided that they hold a file descriptor to a
* pseudo-terminal master device.
*
* This library (or at least parts of it) will hopefully deprecate over
* time, when we provide the <utmpx.h> API.
