Arrgh, yes, of course. I hadn't thought about that... But just change to
copying /etc/resolv.conf instead of copying /run/systemd/resolve/resolv.conf
would work in any case. (That's what you propose below, I think).

Well, depends whether doing sysv of systemd:
- in the sysv book, there are instructions for creating /etc/resolv.conf. No
need to do anything else then, whatever the host configuration... The network
will be available after that. So no need to change anything.
- in the systemd book, we recommend symlinking
/etc/resolv.conf->/run/systemd/resolve/resolv.conf, which does not exist, so
that the network cannot be used. In this case, before entering chroot, and
after $LFS/run has been mounted to a tmpfs, simply add:
mkdir -p $LFS/run/systemd/resolve
cp /etc/resolv.conf $LFS/run/systemd/resolve
I think this should be OK whatever the host. I'll put that into jhalfs.
Whether it should be added to the book is another story. It looks like systemd
users would +1 it, while others are more reluctant. It certainly is only for
systemd...
