Installation is successful, but user data isn't persistent

Users who choose to create partitions manually should understand the following to avoid an erroneous 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.
