NFS home dirs and sudo

[Todd C. Miller]

That shouldn't be a fatal error--at least not in recent versions
of sudo.  Sudo will try to get the current working directory first
as the calling user, and, if that fails, as root.  If that didn't
work it will print "sudo: Can't get working directory!" and continue.
Note, however, that not all command are happy about not being able
to read the current working directory.
