[chef] Re: Fwd: Testing/feedback on Yum provider improvements

[KC Braunschweig < >]

- Applied updates to noted files on a fresh 0.10.0 gem installed
server on RHEL 5.6.
- Bootstrapped a RHEL 5.6 client box and ran some cookbooks on it. No
problems to report. Didn't do much that's particularly wild w/
packages. Mostly standard package definitions in recipes that'll be
handled by yum like:

package "perl-Date-Calc" do
  action :install
end

package "perl-HTML-CalendarMonthSimple" do
  action :install
end

package "sudo" do
  action :upgrade
end

#remove default apache if installed
package "httpd" do
  action :remove
end

#now install custom apache
package "apache-httpd" do
  action :install
end

package "java-1.4.2-gcj-compat" do
  action :remove
end

package "sun-jdk-1.6" do
  action :install
  version node['java']['version']
end
