I also had a problem with the (static) IP configuration file, when I booted for the first time my LFS-7.7-systemd system.
What the book says is correct, but it could maybe be expressed a bit more clearer:
1. As the Note (Udev may assign … your system) says, the output of “ip link” is totally different under LFS from what my host system told me.
The only problem is that I already forgot that Note, when I needed it after the first boot, so it took some time to find the solution
I had to rerun “ip link” and update the IP configuration file.
2. The book suggests that the “Name=eth0” line in the configuration file should be copied as such, but that is not the case. I had to put the “ip link” name there, to make the interface work.
If you want to use “eth0” as interface name, then you must give that name to the configuration file.
This was finally working for me (interface name = “wired”):
root:/sources# cat > /etc/systemd/network/10-static-wired.network << "EOF"
My suggestion: change the command (for a static config) as follows:
cat > /etc/systemd/network/10-static-<your interface name>.network << “EOF”
Name=<interface name, reported by “ip link" under LFS>
