Nope. if you don't have engineers working on the code, you can't
provide the level of service required for an enterprise solution, in
my experience. I don't believe there is conspiracy.

Did you do any database work on the 90s?
Just curious. I know MySQL did not support transactions. I don't
recall when PostgreSQL did. Choices were limited, very limited for
enterprise. Without transactions, you can't trust a database. At least

My recollection is in the 90s the database that ran on Linux that did
transactions were VERY limited-- Oracle and Sybase.

Nope. I didn't make any claim about # of machines or any such thing.

It seems like yesterday to my memory, but in the computer world and
what I can and do do with computers has changed drastically. I hope
you didn't mean you are doing the same thing from 10 years ago w/ the

It is an appliance. It shouldn't matter.
There is a need to provision, patch, manage and report on the servers
in your infrastructure. There is a cost (time, salary, etc) to make
that happen. RHT offers an appliance that assist with that and saves
you money. If it is a turnkey solution that requires little/no
maintenance, the how shouldn't matter. If it does, then roll your own
because you won't be happy with a black box.
So if an appliance doesn't work for you, don't use it.
