    Phoronix: There Is Finally A User-Space Utility To Make EROFS Linux File-Systems

    Back when Huawei introduced the EROFS Linux file-system earlier this year, there wasn't any open-source user-space utility for actually making EROFS file-systems. Even when EROFS was merged into the mainline tree, the user-space utility was still non-existent but now that issue has been rectified...

    Does EROFS need an fsck utility as well?

      Nope, first you would use a tool that works with plain files and not blockdevices.
      And then, its a read-only filesystem, means you would save the source directory if you need backups.

        *lol*

        It's either a happy or messy ending. Depending of the result of fsck'ing... Everyone should use EROS...

          I'm worried EROFS may be a problem for the Android modding scene, as they will have to re-flash the entire partition when doing changes, and wouldn't be able to do them in place...

            Wasn't Huawei locking down all their devices anyway?

              Not really, just put an overlay fs on top.

                Depends on how locked down the bootloader is and how early the init system can be hijacked for overlays to be fully viable on Stock Roms.

                A 100% bootloader unlocked device makes it a moot point because overlays can be used whenever during the init phase plus the file system can be changed to something r/rw on testing/dev builds with the ro file system on official releases.

                  Read the post from tildearrow that I quoted, if they can re-flash a partition they can add an overlay-fs there (or just completely replace the filesystem).

                  But TBH I would guess that Huawei already uses an overlay out of the box. That way you can do stuff like a factory reset really easy (clean the upper layer), and updates would be easier aswell (replace the lower level).
