/etc/systemd/system/getty.target.wants/getty@tty1.service

Original Summary:
eth0 report update as boot completes causes screen to clear, in spite of
--noclean agetty option

This began with TW very long ago and applies to 15.4 and 15.3 as well. 15.2 was
OK.

To reproduce:
1-uninstall or disable Plymouth
2-Include
ExecStart=-/sbin/agetty -o '-p -- \\u' --noclear %I $TERM
in
/etc/systemd/system/getty.target.wants/getty@tty1.service
3-boot without quiet or splash=silent, and with noresume added to, linu line in
grub.cfg

Actual behavior:
1-post KMS-engagement text messages appear onscreen ending with:
a: Welcome to openSUSE...(tty1).
b: eth0:
c: <hostname> login:
2-screen clears to only:
a: Welcome to openSUSE...(tty1).
b: eth0: xxx.xxx.xxx.xxx
c: <hostname> login:
3-EOF

Expected behavior:
1-post KMS-engagement text messages appear onscreen ending with:
a: Welcome to openSUSE...(tty1).
b: eth0:
c: <hostname> login:
2-EOF
