[ale] Red Hat upgrades?

You and I define "stability" differently.   Stability to me means you
can continue to run and get security/bug fixes until you're ready to
move to a new platform.   Often planning and implementing such a move
for complex systems takes more than the 13 months you mention.

 

I am NOT against Fedora.  Fedora is used as a test bed for what ends up
in future RHEL releases and is supported as a project by RedHat and I
use Fedora.

 

A quote on the main page of Fedora Project:

"Since its first version, in 2003, Red Hat's Fedora Linux has been the
best place to track what's on the leading edge of Linux and open source
software."

- Jason Brooks, eweek.com

 

If you'd like to quibble over my use of "bleeding" and his use of
"leading" rather than understanding the congruence between the words as
used in IT feel free.

 

>From Fedoraproject's objectives site:

"Produce robust time-based releases every six months using a release
model that allows the development team the flexibility it needs to
ensure quality, while making sure that a release does not slip
indefinitely. Our schedule may shift from time to time based on
participant needs, but only after consideration and approval by the
community governance entities that oversee the Project."

 

While you are technically correct in saying it is generally not EOL
until after 13 months the fact is that this is considered a SHORT time
for most Production systems as I noted above.

 

I made it clear that RHEL is for commercial use so am not sure why you
seem to be implying I said anything other than that.   My post was
mainly to explain why one can't "just upgrade" from one major RHEL
release to another and was not intended to dis Fedora or any other
distro in any way.

 

P.S. Haven't seen you at AUUG in a while.

I would respectfully disagree with you there.

 

1) Fedora is stable.  It's not bleeding edge unless you are on Rawhide.

That myth is promulgated by people arguing against Fedora.  Fedora is

very much like Ubuntu 6 month.

 

2) You can run at least 13 months.  The Fedora edition is not EOL'ed

until the initial test versions of the +2 edition are posted.  F15 is

out.  F14 is certainly supported and nobody has to upgrade.  F12 was

past it's shelf life and no longer receiving updates, this is true.  But

the repositories are all still out there and I had no problem doing a

smooth, seamless upgrade to F14, passing momentarily through F13. 

 

> In RHEL stability and supportability are the main drivers.

 

Another myth.  I've already dealt with that.  The main drivers are

commercial product deliverables.  Put the stability myth in the dustbin

where it belongs.  You want stability, you got it with Fedora if you go

-1 on the release version.  RHEL 6 is going to have it's amusements and

just WHY do you suppose CentOS has not released version 6 yet?  Yes, RH

made life miserable on Oracle and a couple of others but those others

included CentOS.  Stability is NOT their main objective.
