       I am not familiar with this architecture.  Our Linux load
module area alone in 31DEC00 uses 200 Mbytes of disk.  The libraries
add 12 Mbytes and the source code will take more.  Therefore 164
Mbytes will not do.

     It does take this when one has various data files and the like.
Some of those you already have.  The 500 Mbytes is a deliberate over
estimate to encourage you to have more than enough. Squeezing on disk
is plain silly - it will cost more in your salary and mine than a 20
Gbyte disk.

It depends on what you mean by customization.  The files to control
hosts, disks, tapes, printers and the like are retained and the
general DA00 area control files are the same.  One can do an
installation with install.pl for a single computer and then copy the
control files and make pointers to the DA00 files.  You may find that
simpler than moving the 15APR99 which will probably be abandoned once
a more modern version is installed.
