Without really understanding all that Steve's getting at here, perhaps
my comments aren't appropriate.
Yes, there are problems in attempting to create a VMS environment, and
then "cloning" it multiple times. Nothing is perfect. Some advances in
allowing this might be one solution.
However, and as Jan-Erik mentions here, Some of us may not understand
"customized VMS environments". I don't think that I understand. Well,
I probably do, but consider, outside attempting to clone a system, there
are very few things I do in the way of customization.
To me, you install the system, and it's there. With the exception of
decompressing libraries, setting up node names, DECnet and IP addresses,
and such, it's ready for use.
Now, there is much more to be done in setting up users, setting up
custom symbols and logicals, setting up the applications, and such.
But, I for one don't consider that "customizing" VMS. I also have such
well documented (well, sort of) and in some command files and such. For
instance, and this is not a complete list.
Some things I want in the system startup. When possible, this is one or
more files that are invoked from SYSTARTUP_VMS.COM, and I also have a
SYSTARTUP_BATCH.COM.
Some things I want each user to have. SYLOGIN.COM is one place for
such, and either your own custom command file can replace the
boilerplate file provided with VMS, or, your stuff can be inserted into
the boilerplate command file, or perhaps you call your custom stuff from
the boilerplate command file (which still requires changes).
When possible, NO APPLICATION STUFF ON THE SYSTEM DISK !!!
So I don't see such a big problem. VMS is VMS, if you don't go mucking
with it, and I consider it prudent to do as little mucking as you can
get away with. There will be some, such as SYSGEN parameters, but even
here, if you have 300 systems all doing the same thing, then placing the
common mucking on each system isn't too big of a task.
Is there room for improvement? Always! It's defining useful
improvement that is the task.
Not having to decompress libraries would be a help. It is one reason,
among others, that people try to clone a system disk. If the
installation of VMS gave what is needed without all the special steps,
perhaps people would not attempt to clone so much.
I've got a weendoze utility that sets DST dates. Real easy to use.
Much easier than anything available on VMS. And, this is a simple
application. Why cannot some simple application(s) be provided with VMS
to perform some tasks, such as time set-up, node set-up, and such
things? These would be great improvements. Perhaps some such would
require modifications of the OS to provide such capability. I'd think
not. I'd figure the locations for certain data already exist, it's just
the modification of the data that is less than easy.
But, I don't see being able to avoid site specific customization, on
VMS, or any other OS. At least I cannot. Perhaps others might be able
to do so.
