Slightly wrong, you are also matching non-executable files.
The actual number of init scripts is 1189 as determined by
$ find . -type f -perm 755 | wc -l

Good catch. Of those, ifupdown-extra_0.22/init.d/networking-routes is a
false-positive but the other 9 are valid cases.

Done.

Also done. With the previous version of my patch:
$ systemctl show -p CanReload openarena-server.service
CanReload=no
$ systemctl show -p CanReload pulseaudio.service
CanReload=yes
$ systemctl show -p CanReload libvirt-guests.service
CanReload=no
With the latest (attached) version of my patch:
$ systemctl show -p CanReload openarena-server.service
CanReload=no
$ systemctl show -p CanReload pulseaudio.service
CanReload=yes
$ systemctl show -p CanReload libvirt-guests.service
CanReload=yes
