Original commits are available in http://git.erp5.org/repos/slapos.git
repository.

Same as 0526e075
but keeping erp5testnode because it will go back into this repository.

SlapOS code has been moved to: http://git.erp5.org/gitweb/slapos.git

erp5.recipe.testnode is specific testnode for ERP5,
so it must be in this repository.

The path slapos/recipe/testnode should be much better,
but for now all tools are not ready for it.
slapos/recipe/erp5.recipe.testnode must be renamed
to slapos/recipe/testnode soon.
