[Bug 861388] Re: /usr/bin/who returns no user...

[C de-Avillez]

Thank you for opening this bug and helping make Ubuntu better.

Indeed, 'who' uses data stored on a system file (utmp, for Linux); this
file is populated by other binaries, and its correctness depends on the
binaries. From 'man 5 utmp':

"The utmp file allows one to discover information about who is currently
using the system.  There may be more users currently using the system,
because not all programs use utmp logging."

If a login record is not written, then 'who' cannot report on it.

This is not a bug for 'who'; it could be considered, perhaps, a bug on a
session manager -- I do not know --. You can also look at bug 268780;
comment #3 is more to the point of your bug.

I am unsure on how to proceed here, so I will leave it New. You might
want to add an "Affects" for your session manager.
