- Replace log.Fatalln in goroutines with error returns collected via mutex-protected slice, checked at barrier points and after final wait. - Fix WaitGroup race between mountDrive and mountBindfs by removing the separate Add/Done pair and calling mountBindfs as a plain function. - Fix encrypted+already-decrypted path skipping the mount step entirely. - Add LUKS cleanup (cryptsetup close) when mount fails after decryption. - Close cryptsetup stdin pipe after writing password to prevent hangs. - Only pass -o to mount when Flags is non-empty. - Support RAID_MOUNT_ENCRYPTION_PASSWORD env var as alternative to the command-line flag which is visible in the process list. - Replace deprecated ioutil.ReadFile with os.ReadFile. - Standardize error reporting on log package, remove mixed fmt.Printf. - Fix config path resolution to check flag emptiness before stat. - Add parallel semantics documentation to raidtab.example.
