Hello. We''re running a mix of Redhat and SL, for the same reasons I would guess many others do, which is to say it saves us money on "misc" servers where support contracts, ISV/IHV certification and so forth aren''t needed. I''m curious about how others handle this with regards to Facter and OS detection in manifests? Do you simply add cases for $operatingsystem = Scientific?

It depends on the complexity of your classes.
For a lot of the time you can use variables for the difference between
operating systems and then use conditional logic to populate those
variables, like:
$pkg = $operatingsystem ? {
''RedHat'' => "woof",
''Fedora'' => "meow",
}
package { $pkg: }
I''ve never used Scientific Linux though so I don''t know how
much it
differs from Red Hat. If you have to start doing very different things
between OS versions, some people prefer to conditionally include sub
classes that are geared towards an individual OS:
class stuff {
if ($operatingsystem == ''Fedora'') {
include stuff::fedora
} elsif ($operatingsystem == ''RedHat'') {
include stuff::redhat
}
} else {
fail("The OS ${operatingsystem} is not supported by the
''stuff''
class.")
}
}

That''s exactly how I use the facter facts, my classes aren''t
terribly complex, most of my usage is in the subtle differences, service names,
file locations, etc.
SL is like CentOS, pretty much a respin sans the Redhat trademarks and such. For
my current purposes it''s exactly the same which is the reason
I''m asking.
Regards
Johan

That sounds promising. I''m currently using the EPEL repository to install Puppet, and they''re at 1.6.0. I guess I''ll have to decide what''s less trouble, installing Puppet some other way or rewriting a bunch of manifests. :) Thanks Johan ________________________________________ From: puppet-users@googlegroups.com [puppet-users@googlegroups.com] on behalf of Steve Traylen [steve.traylen@cern.ch] Sent: 14 October 2011 10:19 To: puppet-users@googlegroups.com Subject: Re: [Puppet Users] Re: Redhat and Scientific Linux On Fri, Oct 14, 2011 at 10:05 AM, Luke Bigum <Luke.Bigum@lmax.com> wrote:>> We''re running a mix of Redhat and SL, for the same reasons I would guess many others do, which is to say it saves us money on "misc" servers where support contracts, ISV/IHV certification and so forth aren''t needed. >> >> I''m curious about how others handle this with regards to Facter and OS detection in manifests?

Once it moves to stable, we''ll push 1.6.2. (This process can be sped up if EPEL users snag a Fedora account and use the Bodhi update tool¹ to give positive or negative feedback on updates.) ¹ https://admin.fedoraproject.org/updates -- Todd OpenPGP -> KeyID: 0xBEAF0CE3 | URL: www.pobox.com/~tmz/pgp ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ To grasp the true meaning of socialism, imagine a world where everything is designed by the post office, even the sleaze. -- P.J.

That makes sense in some cases and not in others. I''ve yet to start using this fact in my own manifests, so I''m not sure whether I''ll like it or not. :) -- Todd OpenPGP -> KeyID: 0xBEAF0CE3 | URL: www.pobox.com/~tmz/pgp ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ It''s always darkest just before it goes pitch black. -- Demotivators (www.despair.com)
