CentOS - Aug 2013 - <ask> What is tools for remastering Centos 6 ?

Hi All,

I have fully configured Centos 6.4 machine and my own application inside.
I want to remastering my own machine so that can used to another machine
without any configuration.

Centos 6 ?

Thanks

If the hardware is completely identical you could use dd to write an image of
your hard drive and then just copy it back to the new machine.

You could use revisor to do this, if your application is in an rpm 
form.  This will generate a live CD/DVD using the packages you select 
(not from the running system, but from the packages from which the 
running system was installed).  A user on this list that goes by the 
name of 'nux' has done this with his own re-spin/re-brand of CentOS 
called Stella; so it can be done.  But do note that it's not doing what 
remastersys does.

There isn't, to my knowledge, a remastersys-like system for EL as yet.  
Remastersys does some cool things, but it does put some constraints on 
the system being remastered.  I'm familiar with one such system, A/V 
Linux ( http://www.bandshed.net/AVLinux.html and derived from Debian 
with some customizations) and it works pretty well, but the remastered 
system does have quirks.

For those unfamiliar with remastersys, it allows you to set your system 
up the way you want it to be, and then turns the installed system into a 
liveCD (in a nutshell; there's more to it than that). This can include 
packages built from source, binary blobs, configuration, sample files, 
user settings, etc, and a liveCD is spun from the running system (at 
least that's my limited understanding of it without digging too deeply 
into what remastersys is doing under the hood of my running A/V Linux 
multitrack audio production system, which I use instead of any EL or 
Fedora derived system simply because A/V Linux works with JACK and 
'real' pro audio multitrack cards in a sane way and the 
PulseAudio-crippled EL setup does not and, in the final analysis, cannot 
without lots of work or using different audio devices (I've already paid 
four figures for my audio devices; choice of distribution is dictated by 
the audio device, not the other way around)).

The generated liveCD from the system image is generic enough to boot on 
radically different hardware and still work.  I use very different video 
and audio devices from GMaq (A/V Linux developer) but the 
remastersys-generated A/V Linux liveDVD doesn't care; it just works.

Do note that remastersys itself is, well, a bit difficult to obtain 
right now.  See www.remastersys.com for some more information.

Johnny,

I certainly agree with the idea that the OP should consider making a 
repo of the additional application, but I also understand why something 
like remastersys is useful, being that I use A/V Linux for its 
particular (and not-Internet-connected) purpose in my multitrack 
studio.  There's more to a system than packages, and not all 
customizations are kickstart-able.  And many uses for such don't need 
Internet, and a spun ISO is needed for those instances.

The OP asked a pretty specific question, and the answer to his specific 
original question is probably that revisor will do the closest job to 
what remastersys does of any tool currently available in the CentOS world.

And, in fact, remastersys is no longer readily available from its 
author.  A donation can get the sources, but it was, prior to April 
2013, easily obtained and used.

I'm not so sure that ISO's are 'so 20th Century now' though. 
But that's
a different discussion.  As a reference, see the WSUSOfflineUpdate 
project for Windows.....

You probably want appliance-tools and thincrust:
