[SOLVED] ifup interface eth0: time delay too long without carrier

When I start my other laptop, without a carrier in the eth0, it has a very long timeout of 1 minute, until it proceeds without the interface eth0.
the culprit is here from /var/log/boot

Fri Dec 10 10:42:01 2021: .
Fri Dec 10 10:42:04 2021: Configuring network interfaces...ifup: waiting for lock on /run/network/ifstate.eth0
Fri Dec 10 10:43:09 2021: done.

I found from 'man ip' that ip has a loop counter, default 10 loops, so probably there is a 'sleep' inside as well?

The kernel knows the state of the interface, maybe there can be a shortcut installed to jump that minute ?
from dmesg:

[11912.170762] r8169 0000:02:00.0 eth0: Link is Up - 100Mbps/Full - flow control off

Ask the kernel to check the carrier, before attempting to raise an interface w/o carrier ? Where to fix ?
Ideas are welcome.

Yes that did it.
leaving it to the network-manager to handle all interfaces does the trick.
