[Spacewalk-list] How to use Spacewalk to upgrade RHEL to higher version(s)?

>We'll, unfortunately this isn't the 90s anymore. Things have been
accelerated and we don't have time any more to write 100 pages
documents describing every little detail on how a system is
configured. Even less time to create a document describing how to
rebuild a server that went through 3 different OS incarnations (manual
upgrade fixes included) and 5 generations of junior-type sysadmins
janitoring it.

IBM AIX supports in place upgrades between major releases (5.3 -> 6.1 ->
7.1).  The process is pretty simple and works well with their included
utilities (NIM).

In terms of "what people expect now": most, if not all, of the enterprise
Linux/UNIX users I encounter need a direct upgrade path between major OS
releases.  Rebuilding an environment for each major release takes a ton of
resources: additional servers/VMs, man hours, project planning, etc.

(Sorry if this is off-topic.)
