Hi George,

We use Fedora here at the UPC, but this requires that we update the OS as
Fedora moves to new distributions.  CentOS seems to be a reasonable and
cheap compromise and it fits with what we do since it and Fedora are
RedHat variants.  Given that a growing number of community members are
moving from distributions like Fedora to CentOS, I think that staying with
CentOS makes sense.  On top of that, AWIPS-II is built to run on RedHat
Enterprise 5.5 and will stay with RedHat Enterprise in the future.  Given
that CentOS is a free version of RedHat Enterprise, it would be wise to
stick with it if you have any desire to run AWIPS-II in the future.

See above.

We have no experience in-house with Scientific Linux.  The only feedback we
have gotten about Scientific Linux is from a site (UWisconsin) that ran
into problems with running the LDM with a large queue (>=18 GB) under
Scientific Linux (the LDM would hang after about an hour).  After the
site loaded CentOS on the same hardware, the LDM problem went away.
Is this enough to negate use of Scientific Linux?  Probably not, but it
is an interesting data point...

Cheers,

Tom
