+       help
+         This option allows to explicitly choose which compressions, if any,
+         are enabled in UBIFS. Removing compressors means inability to read
+         existing file systems.
+
+         If unsure, say 'N'.

+          LZO compressor is generally faster than zlib but compresses worse.
