The UEFI init took the first interface in /sys/class/net and put
172.16.9.250 on it. On a PC with a second port, dock or USB NIC that can
be the unplugged one; wget then sat at "Connecting to 172.16.9.1:80"
forever (seen 2026-10-05 on a Dell, serial GGX6BN4). Bring every wired
interface up and use the first with carrier; with no link anywhere,
list the interfaces and drop to a shell. wget calls get -T 30 so a
stalled transfer fails loudly instead of hanging.

Live kexec-initrd.img was rebuilt with only init swapped (backup
kexec-initrd.img.bak-20261005-pre-carrier).
