presets: Disable by default for initrd presets

For initrd presets, we can change the default to disable services
by default instead of enabling by default without breaking compat
so let's do that as it makes much more sense as a default than
enabling everything by default.

+#   unnecessary services that are pulled in that aren't necessary to
