- Update documentation to note `/external` may already be mounted before Ansible runs.
- Avoid redundant ownership and permissions enforcement in `mariadb_primary` role.
- Ensure dashboard service doesn't create an ordering cycle with `multi-user.target`.
- Verify service safely attaches to a virtual terminal (VT) and passes VT to Xorg.
- Ensure no `su` usage by default in the service.
- Validate script behavior for passing VT and `-keeptty` options to Xorg.
chore(dashboard): update systemd unit to avoid VT conflicts and improve logging
- Remove `After` and `Wants` directives for `multi-user.target` to prevent conflicts.
- Add `TTYPath`, `StandardInput`, and related options for VT attachment.
- Ensure `ExecStopPost` restores getty service for the dashboard VT.
fix(dashboard): improve Xorg resolution and clean up script logic
- Dynamically determine Xorg executable location in `dashboard.sh`.
- Pass VT, display, and `-keeptty` to Xorg to improve script reliability.
fix(mariadb): correct exFAT mount options for external storage
- Avoid `chown` failures by setting root ownership with group access for `mysql`.
- Update external mount options to `uid=0,gid=mysql,umask=0002`.
cleanup(mariadb): remove unnecessary owner/group permissions from migration marker task
- Enable mounting borrowed USB disk (exFAT) persistently at `/external`.
- Migrate MariaDB datadir to `/external/mariadb` with bind mount at `/srv/mariadb/mariadb`.
- Add migration marker and rollback support to prevent accidental remigration.
- Include Ansible tasks for external storage setup and migration validation.
