In linux kernel since version 3.10 (release Date: 2013-06-30)  
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, e.g. Android OS
for mobile phones and LIVECDs.

It also provides fixed-sized output compression support,
which improves storage density, keeps relatively higher
compression ratios, which is more useful to achieve high
performance for embedded devices with limited memory.

If unsure, say N.
