/usr/bin/logname do not return proper login name

• Your Windows build number: (Type ver at a Windows Command Prompt)
  Microsoft Windows [Version 10.0.16299.334]

• What you're doing and what's happening: (Copy&paste specific commands and their output, or include screen shots)
  $ /usr/bin/logname
  logname: no login name

• What's wrong / what should be happening instead:
  $ /usr/bin/logname
  rigarash

• Strace of the failing command, if applicable: (If some_command is failing, then run strace -o some_command.strace -f some_command some_args, and link the contents of some_command.strace in a gist here)
  not applicable since the command at least runs smoothly.

If it was running smoothly you'd get the correct output.

open("/proc/self/loginuid", O_RDONLY)   = -1 ENOENT (No such file or directory)

Fundamentally dupe #888 and #1761 (no /var/run/utmp)
