--remove didn't disable

Binary package hint: binfmt-support

Hi

I just renamed qemu-arm-static to qemu-kvm-extras-static and the binfmt-support files from "arm" to "qemu-arm" to match Debian; the former package had in debian/qemu-arm-static.prerm:
if [ "$1" = remove ] && which update-binfmts >/dev/null; then
    update-binfmts --package qemu-arm-static \
        --remove arm /usr/bin/qemu-arm-static
fi

and the new package has in debian/qemu-kvm-extras-static.postinst:
if [ "$1" = configure ] && which update-binfmts >/dev/null; then
    update-binfmts --import qemu-arm
fi

after upgrade, I had only /proc/sys/fs/binfmt_misc/arm in /proc/sys/fs/binfmt_misc/.

After invoke-rc.d binfmt-support restart, I could see both arm and qemu-arm.

It seems to me:
a) binfmt-support didn't disable the arm module when --removing it (but I thought it would)
b) binfmt-support didn't notice that the arm module was gone on restart; not sure whether this could be done though

Is this a bug in binfmt-support, or did the qemu-kvm package get it wrong to start with?

Thanks,

Sorry, that was actually a bug in the maintainer scripts, not in binfmt-support. --remove does work as documented.
