Subject: [PATCH] Setup: remove custom dbuser creation behavior
|
||||
|
||||
Both PostgreSQL and MySQL can be authenticated against from Nextcloud by
|
||||
supplying a database password. Now, during setup the following things
|
||||
happen:
|
||||
|
||||
* When using postgres and the db user has elevated permissions, a new
|
||||
unprivileged db user is created and the settings `dbuser`/`dbpass` are
|
||||
altered in `config.php`.
|
||||
|
||||
* When using MySQL, the password is **always** regenerated since
|
||||
24.0.5/23.0.9[1].
|
||||
|
||||
I consider both cases problematic: the reason why people do configuration
|
||||
management is to have it as single source of truth! So, IMHO any
|
||||
application that silently alters config and thus causes deployed
|
||||
nodes to diverge from the configuration is harmful for that.
|
||||
|
||||
I guess it was sheer luck that it worked for so long in NixOS because
|
||||
nobody has apparently used password authentication with a privileged
|
||||
user to operate Nextcloud (which is a good thing in fact).
