Yes, but we can fix that. In the udev-lfs tarball we have the needed files:
write_net_rules
rule_generator.functions
We need to change two places in rule_generator.functions where it has
RUNDIR=$(udevadm info --run) with a constant RUNDIR=/run/udev
Then in section 7.2 (inside chroot), we need to do a couple of things:
cd ~
mkdir -p /run/udev
cat set_persistent_net_rules.sh << EOF
#! /bin/bash
for NIC in /sys/class/net/eth* ; do
IF=${NIC##*/}
if [ "$IF" == "eth*" ]; then break; fi
export INTERFACE="$IF"
export MATCHADDR="$(cat $NIC/address)"
export MATCHDEVID="$(cat $NIC/dev_id)"
export MATCHIFTYPE="$(cat $NIC/type)"
/lib/udev/write_net_rules
done
EOF
bash set_persistent_net_rules.sh
rm -rf /run/udev
We need to be careful that someone doesn't remove /run/udev after
booting or outside of chroot.
