You found an incompatibility of /sbin/dhclient-script with busybox.
Relevant code snippet:
```
if [ -f $resolv_conf ]; then
chown --reference=$resolv_conf $new_resolv_conf
chmod --reference=$resolv_conf $new_resolv_conf
fi
```
The chown command from busybox does not have a --reference parameter.
Simplified test case:
```
touch resolve.conf
busybox chown --reference=/etc/resolv.conf resolve.conf
```
This also fails for Ubuntu 23.10 (mantic).
Can you document the steps to reproduce it? The amd-net autopkgtest test
cases for initramfs-tools do not trigger the bug (probably because they
to not trigger the if-condition).
** Summary changed:
- PXE Boot - errors in dhclient-script
+ PXE Boot - errors in dhclient-script: busybox chmod: unrecognized option
