-- A perfectly formed autoinstall with upgrade paths for all of
- the intervening versions is not really feasible to implement.
- As such, we want to migrate everything to -scripts, and then
- generate a -scripts2 with the correct .scripts directory.
- We will then nop update some installs, but this will prevent
- us from having to migrate and update concurrently. Treat
- a scripts2 upgrade from migration the same way you would treat
- a botched scripts upgrade.
- ADDENDUM: You MUST NOT migrate to a -scripts2 version; the
- machinery can't actually handle this.
+- It is not expected or required for update scripts to exist for all
+ intervening versions that were present pre-migration; only for it
+ to work on the most recent migration.
