Login delayed by systemd-networkd-wait-online.service

I switched to systemd-networkd.service which works as intended:

erlangen:~ # journalctl -b -u systemd-networkd.service

Configuration of the links being slow, some units will fail due to missing internet connection. Thus I modified them as follows:

erlangen:~ # cat /etc/systemd/system/minidlna.service.d/online.conf 
[Unit]
Requires=network-online.target
After=network-online.target

erlangen:~ # 

The above works as intended and the unit will start only when links are ready. However it has an unexpected side effect on login:

erlangen:~ # journalctl -b -7 -u init.scope -o short-monotonic|grep Started|grep -i login
    5.061921] erlangen systemd[1]: Started Generate issue file for login session.
    5.078849] erlangen systemd[1]: Started Login and scanning of iSCSI devices.

    5.617437] erlangen systemd[1]: Started Login Service.
   ** 9.432681**] erlangen systemd[1]: Started Login and scanning of iSCSI devices.
erlangen:~ # 

Login is delayed considerably. Any idea how to fix this?

So iSCSI connection now waits for network to be up. Where is the problem? How do you expect iSCSI to connect to server if network is not available?

I checked for units:

erlangen:~ # systemctl list-unit-files *scsi*
UNIT FILE        STATE   
iscsi.service    enabled 
iscsid.service   disabled
iscsiuio.service disabled
iscsid.socket    enabled 
iscsiuio.socket  disabled

5 unit files listed.
erlangen:~ # 

Many thanks for pointing to the obvious! :shame:

Ran zypper rm iscsiuio libo*****csiusr0_2_0 open-iscsi yast2-iscsi-client, reinstalled bootmanager and rebooted:

erlangen:~ # journalctl -b 0 -u init.scope -o short-monotonic|grep Started|grep -i login

Login now is possible before graphical target is reached:

minidlna waits for interface when booting, but goes ahead upon wake up:
