This is the problem.

I'm absolutely certain I've seen this bug before but I cannot find it
right now.  Can you try to see which version of libpcap systemd is
linked to?  eg:

$ ldd /usr/lib/systemd/systemd | grep libpcap
  libpcap.so.1 => /lib64/libpcap.so.1 (0x00007f50a9af7000)

You can also see how the supermin appliance is being rebuilt and
whether libpcap is included by doing:

$ supermin --build -v -v -v --copy-kernel -f ext2 /usr/lib64/guestfs/supermin.d
-o /tmp/appliance.d

which will produce a lot of interesting debug output.

I'm not sure of the history of the server's libpcap install.  Too many
chefs and only one pot.  I know, that doesn't help.  Your question did
prompt me to check versions and discover that there's a 1.9.0 version in
the BaseOS repo.  I removed the previous package and loaded the new one.

a quick ldd test
~]# ldd /usr/lib/systemd/systemd | grep libpcap
    libpcap.so.1 => /lib64/libpcap.so.1 (0x00007fc395a38000)

but when I ran virt-sysprep it complains about libpcap again:
"systemd-tmpfiles: error while loading shared libraries: libpcap.so.1:
cannot open shared object file: No such file or directory"

I guess I jumped the gun on updating libpcap.
