Users who create partitions manually should understand the following to avoid an incorrect partitioning setup that can cause data persistence problems in user-managed directories.
⚠️ Important: The root directory is immutable; any directory within the root will be read-only. Do not use a single partition layout. Follow the partition layout as described in Non-automated Partitioning Options.
This problem is neither a Nitrux bug nor a Calamares bug.
