source_remote imageboot.sh is the last thing the diskless cmdline hook runs, so returning early on a failed extraction ended the hook and left dracut to time out. Falling through instead reaches the existing /sysroot/sbin/init guard, which reports the failure and holds the node so it stays reachable over ssh, as it did before extraction was checked.
