We have used it since SL 4.1
As a small engineering manufacturing company we rely on its stability.
As an old Unix guy it was easy.
We have added a lot of packages to it for various Engineering projects
and with Maria DB is runs our manufacturing operation.
We have a few thousand scripts to do odd jobs at night.
We use it as a server for our few Widows machines that cannot be trusted
with critical stuff.
Our file system is huge for a company as we have been shoveling project
files and part libraries into it for 20 years.

We have tried Cent 8 and it is a miserable example of cute but
disfunctional desk top.  It could not be connected to any of our other
machines and the number of mouse clicks to do anything is horrible.

Fedora was a mistake.  Driven by people with no commercial experience.

When the Boss is breathing down your neck and asking why the invoices
didn't go out on time or worse yet is paychecks that are late Friday
Noon and the guys in the shop are not very understanding.

What we have been looking at is PC Linux because it still uses the
traditional Unix boot scheme.  To reorganize something that worded well
with a supervisery bunch of code is nonsense.  So it allows a server to
boot a bit faster.  We reboot our server once every 6 mo.  It's down
just enough to allow a cleaning and checking of fans / filters.  So why
bother.  

So my attitude is bqd but I can rest easy and not worry about a call in
the middle of the night saying the server is down and we need it Monday
@ 7 AM.

The first is that I feel that if I were to report a bug or contribute a fix or answer a question on this mailing list, I would be contributing in some small way to the HEP/SL community. The second is that I feel that the focus and interests of the SL maintainers might be aligned mine. For example, I imagine that a LaTeX problem might be a minor crisis for SL maintainers, but a blip for Red Hat/CentOS. I suppose the decision not to continue SL has been made, but it's a pity. I wonder if it was considered not just as a technical project, but a form of outreach.
