Ubuntu's busybox-static 1.30.1 (which we use for the ARM64 rootfs after piCore64's BusyBox crashes in QEMU virt) doesn't recognize POSIX character classes. `tr -d '[:space:]'` is interpreted as "delete any of the literal characters [, :, s, p, a, c, e, ]" — so every s/p/a/c/e in module names and sysctl keys gets eaten. Symptoms in the boot log: virtio_net -> virtio_nt (e dropped) overlay -> ovrly (e, a dropped) bridge -> bridg (e dropped) nf_conntrack -> nf_onntrk (c, a, c dropped) net.bridge.bridge-nf-call-iptables -> nt.bridg.bridg-nf-ll-itbl Fix: use explicit whitespace chars `tr -d ' \t\r\n'` in both 30-kernel-modules.sh and 40-sysctl.sh. Works under any tr implementation. Also: filter functions.sh out of the init.d stage-copy loop. It's a shared library (sourced by init.sh), not a numbered stage. With it in init.d the main loop runs it as a stage after stage 90, then panics with "Init completed without exec'ing KubeSolo". Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
