      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/

        @poVoq i don't know about the feasability of this, but apps sure are slow to start

          in theory if the kernel has f2fs support built in, and all the utilities to use f2fs are present in the build, then it should be possible, however I dont think anyone has ever actually tried, I had asked about this in telegram a couple months ago and this was the answer I was given, I have been debating if I want to try it or not since then.

            The (better) Android vendors seem to think it is worthwhile... and Google is using it in their flagship phones I think.
            But yeah just a suggestion, might end up to be not worth the effort.
