[SOLVED] Update broke netctl (I guess?)

Hello

After the update of some packages my netctl profile doesn't work anymore.
The interfaces seem to be renamed (again) from before eth0 to ens3, back to eth0.

after 'netctl restart uplink' failed
'journalctl -xn' states:

'ip addr' states

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default
[...]
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
[...]

my netctl profile:

Description='netcup uplink ipv4/6'
Interface=eth0
#Interface=ens3 ### ... WHICH WORKED BEFORE
Connection=ethernet
IP=dhcp
IP6=static
Address6=('someipv6/64')
#Routes6=('someipv6')
#Gateway6=('someipv6')

I already tried the old and new interface-names in the profile, but neither worked.
Now I only can connect if I run dhcpcd, which doesn't work for IPv6.
Any ideas where the problem could be?

/edit
after looking around a bit I found that in /etc/systemd/system there is a file called 'netctl@uplink.service' with this content:

.include /usr/lib/systemd/system/netctl@.service

[Unit]
Description=netcup uplink ipv4/6
BindsTo=sys-subsystem-net-devices-ens3.device
After=sys-subsystem-net-devices-ens3.device

Changing the last to lines to the right interface name made it work again.

BindsTo=sys-subsystem-net-devices-eth0.device
After=sys-subsystem-net-devices-eth0.device

Don't know why systemd changed the name of my interface, but I'm anxious to know when it will do it again.
Works for now. So its kind of solved.
