+ help
+ EROFS(Enhanced Read-Only File System) is a lightweight
+ read-only file system with modern designs (eg. page-sized
+ blocks, inline xattrs/data, etc.) for scenarios which need
+ high-performance read-only requirements, eg. firmwares in
+ mobile phone or LIVECDs.
+
+ It also provides VLE compression support, focusing on
+ random read improvements, keeping relatively lower
+ compression ratios, which is useful for high-performance
+ devices with limited memory and ROM space.
+
+ If unsure, say N.

+ Print EROFS debugging messages and enable more BUG_ONs
+ which check the filesystem consistency aggressively.

+ For daily use, say N.
