Linux, politics, and other interesting things
Systemd has a new way of specifying names for Ethernet interfaces as documented in systemd.link(5). The Debian package should keep working with the old 70-persistent-net.rules file, but I had a problem with this that forced me to learn about systemd.link(5).
Below is a little shell script I wrote to convert a basic 70-persistent-net.rules (that only matches on MAC address) to systemd.link files.
for n in $(grep ^SUB $RULES|sed -e s/^.*NAME..// -e s/.$//) ; do
LINE=$(grep $n $RULES)
MAC=$(echo $LINE|sed -e s/^.*address….// -e s/…ATTR.*$//)
echo "[Match]" > $NAME
echo "MACAddress=$MAC" >> $NAME
echo "[Link]" >> $NAME
echo "Name=$n" >> $NAME
