  12           UBIFS is a file system for flash devices which works on top of UBI.

  18           This option allows to explicitly choose which compressions, if any,
  19           are enabled in UBIFS. Removing compressors means inability to read
  20           existing file systems.

  22           If unsure, say 'N'.

  29            LZO compressor is generally faster than zlib but compresses worse.
  30            Say 'Y' if unsure.

  37           Zlib compresses better than LZO but it is slower. Say 'Y' if unsure.
