Bug#928178: Unusual but legit setup

[Paolo Redælli]

According to th Filesystem Hierarchy Standard "/home is a fairly 
standard concept, but it is clearly a site-specific filesystem. The 
setup will differ from host to host. Therefore, no program should rely 
on this location."

Note [9] also state that "...On large systems (especially when the /home 
directories are shared amongst many hosts using NFS) it is useful to 
subdivide user home directories. Subdivision may be accomplished by 
using subdirectories such as /home/staff, /home/guests, /home/students, 
etc."

So having /home/staff/biff as home directory is allowed. I guess that 
there is some occurrences of an expansion looking like "/home/$USERNAME" 
that shall be changed into "$HOME".
Just my 2¢€
