Update.app: Catch "Installed packages to be REMOVED"
Update.app: Catch Installed packages to be REMOVED and exit with an error to prevent an update to uninstall anything.
This probably means that we need to do pkg upgrade --dry-run (no sudo needed for this!), just to see whether the actual upgrade would remove, aka break, anything.

Not all removals are breakage.
In my definition, they pretty much are: At least if they remove stuff that came with the helloSystem ISO in the first place. That "operating system level stuff" must never be uninstalled, no matter what. (It may be updated, though.)
A CONFLICTS_INSTALL example:

Removals of drm-current-kmod and drm-devel-kmod are by design, not breakage.

They're not integral to helloSystem, but it's an example of one port superseding another.
Removals of drm-current-kmod and drm-devel-kmod are by design, not breakage.
Something that non-technical helloSystem users do not, and should not have to, understand.
What was installed (at the ISO creation time) should never be uninstalled, unless explicitly asked for by the user. But it should be possible to be updated.
This is why I still think package managers are not for "mere mortals" but only for those putting together the ISO, and maybe for power users...
