JJ,
<br />
<br />Is this even open to just club members? Or anyone interested??
<br />
<br />I want to check before mentioning it to CAP or GAPA members - who might want to attend.
<br />

Nope!

EPEL has a lot of things that are incompatible with BlueOnyx. If you
<br />>
activate the EPEL repository and run a "yum update" against it, your
<br />>
server will be dead in the water. The GUI will stop working and lots of
<br />>
other services will also go titsup.com.
<br />>
<br />>
Off and on I like to grab things from EPEL myself. I usually just grab
<br />>
the single RPM that I want and download and install it directly without
<br />>
activating the EPEL repository itself.
<br />>
<br />>
The more complex dependencies that single RPM has, the bigger is the
<br />>
chance that a "yum install" of that RPM will cause issues. So you need
<br />>
to be really, really careful there.
<br />>
<br />>
As for which EPEL version? EPEL5 for CentOS5 and EPEL6 for RHEL6 clones
<br />>
such as CentOS6 and SL6.
<br />>
<br />>
If you really need to YUM install your EPEL stuff and therefore want to
<br />>
install the epel-release-*.noarch.rpm, you must be ABSOLUTELY sure to
<br />>
immediately remove it after you have yum installed your EPEL stuff.
<br />>
because the next time the automated "yum update" runs, it'll break
your
<br />>
box with the stuff from EPEL.
<br />>
<br />>
But like said: Complex dependencies are your enemy. If you try to "yum
<br />>
install" a certain EPEL RPM, check the list of RPMs that it wants to
<br />>
install. Copy and paste it to a file, too. Because if stuff from that
<br />>
list breaks your box, you will want to know what you need to remove
<br />>
(and/or reinstall) from the CentOS/SL/BlueOnyx mirrors to get your box
<br />>
working again.
<br />>
<br />>
So all in all it is possible to install stuff from EPEL. But it requires
<br />>
a lot of caution, because the potential of breaking your box is pretty
<br />>
high.
<br />>
<br />>
That's why we usually don't suggest it.
<br />>
