"""Migrations module.
|
|
Migrations module is introduced in v1.1.1 and provides one-shot
|
|
migrations which cannot be performed from the NixOS configuration file changes.
|
|
These migrations are checked and ran before every start of the API.
|
|
|
|
You can disable certain migrations if needed by creating an array
|
|
at api.skippedMigrations in userdata.json and populating it
|
|
with IDs of the migrations to skip.
|
|
Adding DISABLE_ALL to that array disables the migrations module entirely.
