+# Alpine initramfs doesn't contain dm-mod or fuse module, 
+# and even the worse, the libpthread.so is not included too.
+# So here we directly dump the modloop squashfs file from disk to rootfs.
+# Fortunately, this file is not too big (< 100MB in alpine 3.11.3).
+# After that:
+#   1. mount the squashfs file
+#   2. find the dm-mod module from the mountpoint and insmod
+#   3. unmount and delete the squashfs file
