The same thing happens on openSuSE -- I think it's because of the move to
systemd -- it doesn't maintain the wtmp/utmp stuf..

I don't have utmp, just a smallish wtmp:
So I tried a symlink:

sudo ln -s /var/log/wtmp /var/run/utmp

It's not quite the same, but some things work:

Ishtar:law> who am i
law      pts/1        Aug 26 16:37 (athenae)
Ishtar:law> who
law      pts/0        Aug 26 11:59 (athenae)
law      pts/1        Aug 26 16:37 (athenae)

who -b doesn't work, but uptime does:
Ishtar:law> who -b
Ishtar:law> uptime
17:16pm  up 61 days 12:36,  2 users,  load average: 0.00, 0.06, 0.11

So has debian been moving to systemd as well?
