Dear maintainer:

I tried to build this package in buster but it failed:

--------------------------------------------------------------------------------
[...]
 debian/rules build-arch
dh build-arch --parallel
dh: Compatibility levels before 9 are deprecated (level 7 in use)
   dh_update_autotools_config -a -O--parallel

	cp -a debian/grub-extras/$extra debian/grub-extras-enabled/; \
done
env -u DH_OPTIONS GRUB_CONTRIB=/<<BUILDDIR>>/grub2-2.02+dfsg1/debian/grub-extras-enabled \

--------------------------------------------------------------------------------

The build was made with "dpkg-buildpackage -B" in my autobuilder.
Most probably, it also fails here in reproducible builds:

https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/grub2.html

where you can get a full build log if you need it.

If this is really a bug in one of the build-depends, please use reassign and affects,
so that this is still visible in the BTS web page for this package.

Thanks.
