Every time you download a RPM package for installation / updation via yum in Centos / Redhat system it gets deleted automatically after the procedure. Its a rather handy process by which your systems does not waste space storing the installation files.

Want to keep those packages in your system, and maybe create a local repository?

Well there are several ways. Simplest of them would be to edit the yum configuration file.

Many a times I wanted to create my own customized ubuntu, why???

Well 3 reasons

1. I hate having to download the same set of softwares over and over gain, while I reinstall OS.
2. Lot of my friends want the same set of softwares that I use, so making an ISO will help those out without a stable and unlimited net connection. I think its cool.
3. So I have decided to make my own customized ubuntu with lot of programming tools, documentations and compilers added on to it by default. Its the same Ubuntu itself, no change in the internal structure. (Just that we can have more software at the first installation itself)

To build such a version is actually easy, there is a software/tool called Ubuntu Customization Kit. So hackers out there why don’t you give it a shot.

Don’t know if it is the best way to start, but here it goes…

I am starting a technical blog, something that I wanted to do for a while…

So wish me luck =)
