MariaDB 10.11 rootless fails on mysql_upgrade --force, stepmysql_fix_privilege_tables

[AlexSkrypnyk]

I've been trying to get the mariadb 10.11 image working with imported DB for a rootless user and have found that mysql_upgrade --force always fails on mysql_fix_privilege_tables for the first time but then runs okay for the second time (I have modified the entrypoint during my experiments).

I found this explanation:

Starting from mariadb-upgrade 2.0, the user running the upgrade tool must have write access to datadir/mysql_upgrade_info, so that the tool can write the current MariaDB version into the file. mariadb-upgrade (or mysql_upgrade) was updated in MariaDB 10.2.42, MariaDB 10.3.33, MariaDB 10.4.23, MariaDB 10.5.14, MariaDB 10.6.6, MariaDB 10.7.2 and newer.

Questions:

1. Are there any tests for that branch of the entrypoint that is dealing with the "MySQL directory already present" case?
2. Have you tried to run mysql_upgrade --force for that case with rootless user for 10.11?

Workaround

mysql_upgrade --force||mysql_upgrade --force
