bootstrap.sh sets up a region on a fresh Debian 13 host (packages, PostgreSQL, TFTP tree, config, services, verified commissioning image, provisioning subnet with ranges/DHCP, optional NAT, first OS image). rollcall doctor checks an installation and says what to fix, including a DHCPDISCOVER probe for foreign DHCP servers. pxelinux-default no longer hard-codes the lab address.
