contained in the DHCP offer, and write it out to the lease file as an unquoted value of the "next-server" keyword. The value is ignored when the lease is read back by dhclient, however other applications are free to parse it. The intent behind this change is to allow easier interoperability with automated installation systems e.g. Cobbler, Foreman, Razor; FreeBSD installation kernels can automatically probe the network to discover deployment servers. There are no plans to MFC this change unless a backport is specifically requested. The syntax of the "next-server <ip>" lease keyword is intended to be identical to that used by the ISC DHCPD server in its configuration files. The required defines are already present in dhclient but were unused before this change. (Note: This is NOT the same as Option 66, tftp-server-name). It has been exercised in a university protocol testbed environment, with Cobbler and an mfsBSD image containing pc-sysinstall (driven by Cobbler Cheetah templates). The SYSLINUX memdisk driver is used to boot mfsBSD. Currently this approach requires that a dedicated system profile has been created for the node where FreeBSD is to be deployed. If this is not present, the pc-sysinstall wrapper will be unable to obtain a node configuration. There is code in progress to allow mfsBSD images to obtain the required hints from the memdisk environment by parsing the MBFT ACPI chunk. This is non-standard as it is not linked into the platform's ACPI RSDT. Reviewed by: des |
