> Which zLinux distributions are you using, and why did you
> pick that one?

1) Marist 2.2-vintage distribution

   Because people still ask questions about it.

2) SuSE 7.0

   Because people still ask questions about it.

3) SLES 7

   Because there are a lot of early adopters who haven't upgraded to
SLES 8 yet.

4) SLES 8 (assorted patch levels)

   Because most people running Linux on Z and 390 are on this release.

   Because many customers run IBM middleware on this release.

5) RH 7.2

   Because many corporate users have RH Intel site licenses and prefer
to stay with a single vendor or distribution enterprise wide.

   Because many corporate users have RH maintenance contracts that
include "all future releases" and thus don't have to pay extra for the
maintenance contract on the Linux on Z system

6) RH AS 3.0

   Because many corporate users have RH Intel site licenses and prefer
to stay with a single vendor or distribution

   Because many corporate users have RH maintenance contracts that
include "all future releases" and thus don't have to pay extra for the
maintenance contract on the Linux on Z system

Because I need to support customers with IBM middleware on RH

Because I have to support Tivoli products, which can't seem to
understand that Linux != RH.

7) Debian

   Because it's inexpensive, stable, and well-maintained.

   Because it's usually more up to date than RH

   Superior package management and deployment capability.

   Most packages built for RH "just work"

   Because I rarely need the IBM middleware for research purposes.

My speculation is: two reasons.

Reason 1: They have relatively few S/390 and zSeries customers (a
problem of their own making if you actually listen to their field sales
people) and thus need to extract the maximum revenue from each customer
to stay in the game.

Reason 2: Support people capable of dealing with S/390 hardware are not
inexpensive or easy to find. Something has to pay for this. (this is
true for SuSE as well).


OF course, you do have alternatives to their support (can't dodge the
maintenance, but support is another story).
