The initrd has been rebuilt and eth4 and eth5 are gone.

eno1 and eth3 are still present, i.e. the original problem (2
onboard interfaces supposed to be renamed to eno1) is still
unresolved. The workaround is to kick out "onboard" in the
NamePolicy, e.g.:


# cat /etc/systemd/network/98-ignore-onboard.link
[Match]
OriginalName=*

[Link]
NamePolicy=keep kernel database slot path
AlternativeNamesPolicy=database onboard slot path
MACAddressPolicy=persistent


(https://www.freedesktop.org/software/systemd/man/systemd.link.html)


Do you think it would be reasonable for udev to use the next option
from the name policy list instead of falling back to the "kernel"
policy, if there is a conflict?


Thank you very much for your support and your patience
