Re: uptime (coreutils)

[Roland McGrath]

who and w have always been different things.  who is fine as it is and has
nothing to do with w.  We have the Hurd's w and uptime because they are
better than other versions.

As to functions like fetch_boot_time, if they are useful to applications
that aren't Hurd-specific, then they are useful to specify somewhere or
other in an OS-independent fashion.  That could be just gnulib, or perhaps
glibc's libutil for this particular kind of thing.  But it's only
worthwhile if it's a single interface that many things will actually use.
