I've posted a fix here: https://salsa.debian.org/kernel-team/initramfs-tools/-/merge_requests/203 It adds IPCONFIG_TIMEOUTS to configure the timeout sequence and IPCONFIG_RETRY=y to keep retrying until dynamic configuration succeeds. The defaults stay unchanged. The package builds with sbuild. In QEMU, the client obtained an address when DHCP became available after 20 seconds. I haven't tested the full remote-unlock flow. - Troy
