I will try it.

By the way, the libguestfs src can't build one available base.img and
daemon.img.

#ll /usr/lib64/guestfs/supermin.d/
total 1752
-rw-r--r-- 1 root root    1536 Sep 27 14:39 base.img    <----- it can't work.
-rw-r--r-- 1 root root 1760768 Sep 27 14:39 daemon.img
-rw-r--r-- 1 root root   10772 Sep 27 14:39 hostfiles
-rw-r--r-- 1 root root    4608 Sep 27 14:39 init.img
-rw-r--r-- 1 root root    2048 Sep 27 14:39 udev-rules.img
