Why would you want to build a CEntOS based miner?
CEntOS is the "Community ENTerprise Operating System". What happened about 15 years ago is that many many people using Linux were using RedHat based distributions like Fedora (free desktop version) and the "commercial" version called RedHat Linux. Then, all of a sudden, RedHat decided they wanted to charge $1000 plus per machine for the commercial version and it made people mad. So they went off and created a mirror of the RedHat Linux system and they call it CEntOS.
The beauty of this OS over other choices is that it is designed to operate in a production environment. You can even buy commercial software to run on these servers from suppliers like Oracle and Adobe. Because of the planned cycles the software is stable, unlike most other flavors of linux who are trying to constantly do the "latest" thing people who run enterprise software on their systems are much more interested in reliability. These distributions (Centos, Fedora, Redhat, Scientific Linux) are the best choice for multiple-gpu cards and multiple-gpu systems, especially when there are only windows drivers available for the video card you own.
Here's the instruction sheet. Let me know what can be improved.
Current stable working version combination is SDK 12.7 and Catalyst Driver 12.3.

## important note on installing AMD Drivers under linux:
##
## be certain you have the kernel-devel for YOUR kernel
yum list installed | grep kernel-*
##
## check your distribution
uname -r
##
## you can have multiple kernel-devel's
## if you are lucky this command works
yum install kernel-devel-$(uname -r)
####******#*#*#*#*#*##*#*
## if not you'll need to find another kernel
## with a matching kernel-devel package
yum --showduplicates list kernel-devel
## to download a specific package just add
## the version to the name, for example if
## I want kernel-devel 2.6.32-358.el6 I
## just add a hyphen
#yum install kernel-devel-2.6.32-358.el6
#### "GENERATE DISTIBUTION SPECIFIC PACKAGE"
### Move to package directory
cd /home/miner/miningpacks/
chmod u+x *-driver-installer*
sh amd-driver-installer-12-3-x86.x86_64.run #downloaded above
#### using menus generate RPM package for your OS
#### Install generated package
cd /home/miner/miningpacks/
yum -y install fglrx64_p_i_c-8.951*
aticonfig --adapter=all --initial --force
reboot

#### Test ATI Driver Installation

##
##[Message] Kernel Module : Precompiled kernel module version mismatched.
##[Error] Kernel Module : Kernel module build environment not found - please consult readme.
