Libguestfs - Aug 2013 - Re: --disable-appliance creates supermin.d files

Why does the toplevel Makefile process appliance/, and creates
supermin.d during make install, whith configure --disable-appliance?  I
have to double check what actually happens, it seems it causes startup
failures if the resulting binary packages are started on a host that
happens to have supermin installed.

This seems to be a bug.  I don't think there's anything in the
appliance/ directory which is relevant if --disable-appliance is
specified, and I guess the line:

superminfsdir = $(libdir)/guestfs/supermin.d

is processed when make install is called.

What happens is that ext2_lookup fails for me. The package is build with
        env \
        QEMU=/usr/bin/qemu-kvm \
        SUPERMIN=supermin \
        SUPERMIN_HELPER=supermin-helper \
        ./configure --disable-appliance

So the question is: should --disable-appliance just not create the
appliance during "make", or should it also remove all supermin support
from the resulting binaries (by not creating supermin.d)?
