It took many hours to get it installed because of all the patches
that had to be applied, and that process was very far from automatic.
When you download Linux, you spend a long time trying to find the
files that are not in the right places. That initial barrier stops
a lot of people who initially tried Linux. Cafeteria rumors state
that this is typical of all un*x-like operating systems.

I have gotten past that stage, and am now ready for a release of
gnat that fixes the packed arrays problem. Then I will try Linux again,
to see if it run software like interrupts and realtime control of
the ports, faster than DOS.

I believe that the company Red Hat has a commercial version of Linux
that is advertised as easy to install, but I have no experience with it.
When you were talking about ease and reliability, perhaps you were
talking about the commercial version of Linux.

For purposes of most Ada programmers, they have a very limited amount
of time to spend installing patches to operating systems, and getting
around artificial limitations built into products (interrupts, ports, etc.).
