shellcheck / shellcheck (push) Failing after 17s
When configure had nothing left to do, install.sh ended on the kernel check and the firewall's warnings just above it, so a successful run could be taken for a failure. Move the end of install.sh to system/finish-install.sh, which now says the install worked before the reboot advice and configure offer, and test it.
