How to install exactly the same packages on another computer in openSUSE

cloningopensusepackage-managementsoftware installation

Another computer can be as well virtual machine. I cannot make disk clone because of hardware differences and settings.

I have computer A, installed and running, I also have computer B. I will install the same OS on B, so I would get the same base system.

Then by hand I will add the same repositories as on A.

But the last stage is beyond me — how to install the same packages as on A? Note, that the version has to match, not only package name.

Of course I am looking for automatic way, not installation manually one by one.

In effect I should get completely different hardware configuration, clean settings (no old passwords, etc), but identical software selection.

Question

How to do it?

Background

The packages (per version) are available but are not the latest ones. The point of this is to make a "copy" of running system, upgrade packages on computer B (copy), test if it works, if yes, then upgrade A. With every new OS version I am hit by many regression bugs, and I have to test it more methodically, than test-live & panic.

openSUSE 11.4

Best Answer

Sounds like you have to build your own repository.

Put your RPMs in your desired version into that repository. Then activate these repositories on both machines (as installation source) and install the packages.

How to install mercurial on openSUSE

Check if you have yum installed by typing yum --version in your terminal prompt. If you get something with a version number then you have it installed.

sudo yum install python - should install python.

Likewise, sudo yum install mercurial - should install mercurial.

EDIT-1: In case if you are not comfortable with command line method, open up the package manager and search for both of them and install it that way. My guess is you don't have to download the rpm and install python or mercurial. It should be available with the distro package manager itself.

EDIT-2: If you want to search for a package use - yum search <insert-package-name-here>. If you don't know the full package name you can just use a part of the package name.

Other command is yum whatprovides <package-name>. For more commands refer here and here.

How to install Scala

From the README file in

 cat /opt/scala/doc/README

I took this:

Scala Software Distributions
----------------------------

- scala-<major>.<minor>.<patch>.tar.bz2     Unix distribution
- scala-<major>.<minor>.<patch>.tar.gz      Unix distribution
- scala-<major>.<minor>.<patch>.zip         Windows distribution

The standard distributions require Java 1.5 or above. If you don't
know which version of Java you have, run the command "java -version".


Scala Tools
-----------

- fsc         Scala offline compiler
- scalac      Scala compiler
- scaladoc    Scala API documentation generator
- scala       Scala interactive interpreter
- scalap      Scala classfile decoder 

Run the command "scalac -help" to display the list of available
compiler options.


Unix Installation
-----------------

Untar the archive. All Scala tools are located in the "bin" directory.
Adding that directory to the PATH variable will make the Scala commands
directly accessible.

You may test the distribution by running the following commands:

$ ./bin/sbaz install scala-devel-docs
$ ./bin/scalac doc/scala-devel-docs/examples/sort.scala
$ ./bin/scala examples.sort
[6,2,8,5,1]
[1,2,5,6,8]
$ ./bin/scala
scala> examples.sort.main(null)
[6,2,8,5,1]
[1,2,5,6,8]
scala>:quit
$

(omitted: Windows-notes)

Does this take you a step further?
