Package: libguestfs0
Version: 1:1.36.13-1+b2
Severity: important
--- Please enter the report below this line. ---
With dash installed as /bin/sh, the supermin "appliance"s ends up being
built without a /bin/sh (as of bash 4.4.18-1, since bash drops the
pre-depends on dash).
This sort-of wrecks havoc with the qemu VM via virt-* commands (e.g.
virt-rescue -a debian-9.img --network -r), particularly those using
networking, because dhclient-script uses #!/bin/sh.
adding 'dash' to /usr/lib/x86_64-linux-gnu/guestfs/supermin.d/packages
fixes the issue (though that may not be the correct packaged fix)
On Debian 9.3, supermin's build log shows that it includes dash:
/usr/bin/supermin --build \
--verbose --verbose --verbose \
--lock /var/tmp/.guestfs-1000/lock \
--copy-kernel \
-f ext2 \
--host-cpu x86_64 \
/usr/lib/x86_64-linux-gnu/guestfs/supermin.d \
-o /var/tmp/.guestfs-1000/appliance.d

On an up-to-date sid system, supermin's build log is missing dash:

With /bin/sh as dash, the "appliance" ends up being built in a way that
networking fails:

(as a side note: on my system, I also have to link up eth0 in the qemu
guest before dhclient works, but I'm still investigating that. I don't
know if I've mucked something up or it's an issue with newer dhclient or
qemu or kernel or what.)
