The kernel commandline syntax for `nbdroot=...` changed.
2017-03-28Use pxelinux "ipappend" option to choose rootfs sourceAndrew Cady
This fixes the issue described in the first 'netkeys' commit, where the network would need to be available even when it was not used. The "ipappend" option results in a $BOOTIF variable in the initrd environment. This variable is now used to determine whether to wait on the network for a rootfs & keys, or to wait on the boot device becoming available to determine whether it has the keys. That is, there may or may not be a boot device which may or may not have keys and/or rootfs, but we will always know for sure whether it does, therefore there are no races and no waiting on the network unnecessarily. The qemu.sh script was updated to provide the BOOTIF variable when PXE boot is emulated.
2017-03-28Implement boot parameter "netkeys"Andrew Cady
This allows the keys to be loaded from the boot medium even when the root filesystem is loaded over the network. I.e., specifying nbdroot= no longer implies that the keys will be loaded over the network. The ISO images generated by xorriso-usb.sh will not specify 'netkeys' so the keys on the USB stick will be used. The idea is that after install, the network should not be needed at all; but that requires using a new mechanism instead of the nbdroot= parameter, to determine dynamically whether to use a network root fs device. Currently, the network is still needed to boot a device that has its root fs on the local disk and the keys on the boot medium, even though no data is fetched from the NBD server. You can force the machine to boot by going to the initramfs shell and running: for n in $(seq 1 20); do killall ipconfig; done Otherwise it blocks waiting for the network.
