[Planetlab-users] getlogin() returns null

[Stephen Soltesz]

errno:   ENOENT,  There was no corresponding entry in /var/run/utmp.
/var/run/utmp is an empty file.  :-)

This wasn't my code using getlogin().  I've worked around it.  So, just 
FYI, if this is a concern for other.

Thank you,
Stephen.
