** Description changed: Building an ubuntu-cpc minimal image by default would have no snaps installed. When I binary hook seeds a snap that has a core18 base the build will fail when calling 'snap debug validate-seed' because the snapd snap is missing. Additionally, an image with snaps that only depend on core18 (which isn't in the ubuntu-cpc:minimized project) would still ship 'core'. - This was found by code inspection. + This was found by code inspection and reported in bug #1871912. We want to build images that only contain the appropriate core image and when that is not core it should have snapd preseeded. The _snap_post_process function is meant to install snapd if core18 is the only core snap installed or remove snapd if core is installed and snapd was not explicitly installed. But the current logic in _snap_preseed will never call _snap_post_process. $core_name will never be empty with the existing logic, and even if it were that would only be for the 'core' snap and we'd miss using the 'core18' logic that pulls in snapd. Given the case statement in _snap_post_process can handle doing the right thing given any snap we can just call it unconditionally. Seeding any snap via snap_preseed will evaluate the base for each snap and seed the appropriate base. There should be no reason to explicitly seed the 'core' snap and with snaps moving to 'core18' this will add 'core' without need.
