| 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. | |
| Say 'Y' if unsure. | |
