Title:
DROPBEAR_IFDOWN=* takes interface down but leaves netplan config
Status in clevis package in Ubuntu:
Confirmed
Status in dropbear package in Ubuntu:
Confirmed
Status in initramfs-tools package in Ubuntu:
Confirmed
Bug description:
On bionic, setting the network interface up (e.g. eno1) with DHCP now
causes a /run/netplan/eno1.yaml and a /run/net-eno1.conf file to be
written. The former gets imported by netplan after boot and causes the
DHCP lease from the initrd to be around forever, which I think goes
against the intent of DROPBEAR_IFDOWN=*.
I have brewed up a workaround script that lives in /etc/initramfs-
tools/scripts/init-bottom/hack-delete-netif-netplan.sh for now:
#### ---- 8< cut >8 --------
#!/bin/sh
PREREQ=""
prereqs() {
echo "$PREREQ"
}
case "$1" in
prereqs)
prereqs
exit 0
;;
esac
. /scripts/functions
log_begin_msg "Deleting all network configuration that systemd could try to
import"
rm /run/net-*.conf
rm /run/netplan/*.yaml
log_end_msg
#### ---- 8< cut >8 --------
I think that dropbear-intiramfs's init-bottom script should do this in
addition to downing the interfaces that it finds via the
DROPBEAR_IFDOWN pattern. Do you agree?
