hardcoded "yum install" commands for OS packages in generated container recipe #2923
Description
The currently generated container recipes always use "yum install" to install additional OS packages.
This should be changed to the correct commands based on the Linux distribution being used, for example apt when debootstrap is used as a bootstrap agent.
We also need to figure out a way to specify the correct command when an existing container image is used as a base, perhaps by querying the OS used by that image somehow?
