The installed distribution is useful in a heterogeneous environment due to the properties of local public installation directories like `/usr'. `/usr' is local to each machine, even machines of the same architecture. However, subdirectories of `/usr' can be symbolic links to other locations on disks shared throughout the network.
The HUT creation process (and the Cygnus progressive installation process) suggests the symbolic link
ln -s /usr/cygnus/progressive/H-hosttype /usr/progressive
on each host for which the toolkit is installed. This way, users on each system have access to the Developer's Kit through `/usr/progressive/bin', since `/usr/progressive' on each hosttype points to the binaries for that hosttype.
