get_username() reads file /etc/passwd to get user name.

its actually get_user_id_from_username() doing it

This is not working on system using NIS or LDAP or any other system that has the user information not in the /etc/passwd file. The user do not exist and the string in empty then mainline is trying to open/use the cache in / instead of in ~/ the home directory of the user.

you have to use the glibc function getpwuid() getpwnam() for this to work correctly on all linux systems.

Thanks I'll look into it. I'm away on vacation for a few more days so maybe not immediately.
