Public bug reported:
This failure was detected while working on the amd64-net autopkgtest for
initramfs-tools. Create a dummy root file system and launch qemu with
user network and specify ip6=dhcp on the kernel command line:
```
qemu-system-x86_64 -m 1G -drive
"file=${ROOTDISK},if=${ROOTDISK_QEMU_IF},media=disk,format=raw" \
${USRDISK:+-drive
"file=${USRDISK},if=${USRDISK_QEMU_IF},media=disk,format=raw"} \
-nographic -no-reboot -kernel "/boot/vmlinuz-${KVER}" -initrd
"${INITRAMFS}" \
-device
"virtio-net-pci,netdev=net0,bus=pci.0,addr=3,mac=52:54:00:65:43:21" \
-netdev
"user,id=net0,net=10.0.3.0/24,ipv6-net=fec7::/48,hostname=pizza,dnssearch=test,domainname=example.com,bootfile=/path/to/bootfile2"
\
-device
"virtio-net-pci,netdev=net1,bus=pci.0,addr=5,mac=52:54:00:12:34:56" \
-netdev
"user,id=net1,hostname=goulash,dnssearch=example,dnssearch=example.net,domainname=test,bootfile=/path/to/bootfile"
\
-append "root=/dev/${ROOTDISK_LINUX_NAME} ro console=ttyS0,115200
ip6=dhcp"
```
/sbin/dhclient-script fails. Running the script with "set -x" shows the
culprit:
```
+ ip -6 addr flush dev ens5 scope global permanent
ip: either "dev" is duplicate, or "permanent" is garbage
```
The busybox ip command does not support the FLAG "permanent".
