Thanks, I missed the last paragraph previously.
The reason is the following in the preinst (which I inherited, so if
it is wrong, I gladly rewrite/improve):
case "$1" in
upgrade|install)
if ! LC_ALL=C update-alternatives --display asclock 2>&1 | grep 'error: no
alternatives' > /dev/null ; then
update-alternatives --auto asclock
update-alternatives --remove asclock $asclock-4bpp
update-alternatives --remove asclock $asclock-8bpp
update-alternatives --remove asclock $asclock-24bpp
fi
;;
abort-upgrade)
;;
*)
echo "asclock preinst called with an unkown argument: $1" >&2
exit 1

IMHO this should only be a problem if asclock becomes a build dependency
for other packages which I currently don't see to be.
