Here is my understanding of how x86 FreeBSD network boot works on a high level. First, the initial PXE client must be instructed to load and run FreeBSD pxeboot. pxeboot is a special loader, an intermediate stage that loads the actual FreeBSD kernel. pxeboot is itself a DHCP and PXE client. In a typical setup pxeboot uses NFS for access to its configuration files, the kernel and kernel modules. In that case pxeboot does want to get a root-path in an offer, that's where it gets an NFS share path. When pxeboot is ready to run the kernel, pxeboot passes the DHCP lease information and the NFS path information to the kernel, so that the kernel can properly configure its network interface and mount the root filesystem over NFS. -- Andriy Gapon _______________________________________________ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
