+Sets up tftp pxe config and nfs server on host "faiserver".
+
+If our kernel has no nfs support, uses apache intead of nfs, and depends
+on another repo of Ian Kelling, basic-https-conf, where the file is at
+/a/exe/web-conf.
+
+Usng this, you can boot into fai with pxe-kexec without changing
+the dhcp server.
+
+Argument sets the host to enable it for.  No argument disables pxe
+config for all hosts, but leaves nfs server alone. Use faiserver-disable
+to disable the nfs server.

+-S          sets FAI_ACTION=sysinfo, and remove fai flag reboot.
