timocapa Posted January 6 Share Posted January 6 unRAID currently ships `bzmodules` and `bzfirmware` as SquashFS, however another read-only filesystem exists called EROFS, which should only be slightly bigger in image size than SquashFS, however it should be much faster, potentially translating to faster boot times. Everyone should gain from this, so I think it might be worth looking into.
