<![CDATA[Support for F2FS file system?]]>https://en.wikipedia.org/wiki/F2FS
Seems like this kernel level file system is widely used in the Android world and can offer quite significant speed improvements* (and other advantages) over EXT4 that is currently used in UT.

(While overall performance seems to highly depend on the benchmark, application start-up time measured seems significantly better with F2FS, which would be probably noticeable on UT, which IMHO suffers from relatively slow application startup.)

Has this been considered?

Edit: Hmm, seems to require at least kernel 4.4 (edit: appears to be supported kernel 3.8 onwards?), but some older Android kernels might be patched for it already. See also: https://forum.armbian.com/topic/4167-f2fs-revisited/

But yeah just a suggestion, might end up to be not worth the effort.
