Package: anacron
Version: 2.3-34
Followup-For: Bug #1019554
Dear Maintainer,
It seems that those
symlinks(/etc/systemd/system/multi-user.target.wants/anacron.service and
/etc/systemd/system/timers.target.wants/anacron.timer) are not "dangling". My
testing in a debootstrap sid shows that installing anacron=2.3-32 will create
those symlinks and purging the anaron package will remove those symlinks. It
seems that those symlinks are handled by deb-systemd-helper in
anacron.post{inst,rm}:
segment in anacron.postinst:
# Automatically added by dh_installsystemd/13.9.1
if [ "$1" = "configure" ] || [ "$1" = "abort-upgrade" ] || [ "$1" = "abort-decon
figure" ] || [ "$1" = "abort-remove" ] ; then
# This will only remove masks created by d-s-h on package removal.
deb-systemd-helper unmask 'anacron.service' >/dev/null || true
# was-enabled defaults to true, so new installations run enable.
if deb-systemd-helper --quiet was-enabled 'anacron.service'; then
# Enables the unit on first installation, creates new
# symlinks on upgrades if the unit file has changed.
deb-systemd-helper enable 'anacron.service' >/dev/null || true
else
# Update the statefile to add new symlinks (if any), which need
to be
# cleaned up on purge. Also remove old symlinks.
deb-systemd-helper update-state 'anacron.service' >/dev/null ||
true
fi
fi
# End automatically added section
segment in anacron.postrm:
# Automatically added by dh_installsystemd/13.9.1
if [ "$1" = "remove" ]; then
if [ -x "/usr/bin/deb-systemd-helper" ]; then
deb-systemd-helper mask 'anacron.service' 'anacron.timer'
>/dev/null || true
fi
fi
if [ "$1" = "purge" ]; then
if [ -x "/usr/bin/deb-systemd-helper" ]; then
deb-systemd-helper purge 'anacron.service' 'anacron.timer'
>/dev/null || true
deb-systemd-helper unmask 'anacron.service' 'anacron.timer'
>/dev/null || true
fi
fi
# End automatically added section
deb-systemd-helper is included in the init-system-helpers package, which is a
essential package meaning it will be installed in all Debian system. So those
symlinks will be purged when the anacron package is purged.

And concerning your proposed changes, it seems to me that if anacron.service or
anacron.timer were disabled, these rm will cause anacron.postrm exited with
error.
So I think there is no need to manually handle those symlinks and
anacron.postrm should be reverted to the 2.3-32 revision.
