Instead of utilizing a contextualprocess to only bind-mount /cdrom to
/media/cdrom when it's a specific type of system, simply add it to the mounts
for all flavors, and move the specific copy of the vmlinuz file to a dedicated
shellprocess module. This will be re-factored next cycle, ideally being worked
directly into a dedicated C++ module instead of several, miscellaneous shell
scripts wrapped in YAML.
