What is a minimal "orthogonal basis" for RHEL 6.1?

Latest response

We wish to deploy the simplest possible RHEL.  Is there a strategy for determining which RPMs are essential for basic functionality?

Subject says it all. Start with the Base yum group, and add/remove as necessary.

If you are looking for more minimal then that, take a look at this post:

You could use the redhat-lsb package pull in minimal programs and libraries for a system. The redhat-lsb packages in RHEL-6.1 wont work for you, since they have been modified to pull in redhat-lsb-printing and redhat-lsb-desktop as well (broken lsb-4.0 standards -- it puts some printing and desktop packages in core as well. See https://bugzilla.redhat.com/show_bug.cgi?id=585947).

 

If you're looking to use redhat-lsb to build your minimal system then you may want to follow this route:

 

* Install using redhat-lsb from rhel-6.0 (redhat-lsb-4.0-2.1.el6)

* Remove the redhat-lsb package

* Update your system to rhel-6.1 using 'yum update'
