   If a filesystem mounted to w32 is exported from a server by CIFS/SMB
protocol -- is it case sensitive? What if said server is Linux? What if
said filesystem was actually imported to Linux from a Novel server by
NetWare Core Protocol. It's not a fictional situation -- I do it at
oper.med.ru; the server is Linux that mounts two CIFS and NCP filesystem
and reexport them via Samba.
