 fai kexec from upstream live cds, i.e. curl|bash
 
+If HOST argument, ssh to root@HOST before doing kexec. This does what
+pxe would do, but skipping boot sequence up to and including the pxe
+dhcp.

 You can copy this to a http server, then wget -O- url|sudo bash
 curl is sometimes not preinstalled on a live cd.
 
-This has been tested on trisquel belenos and ubuntu xenial & 18.10.
-With 18.10 on an x200, kexec was unreliable, resulting in freezes and
-kernel panics.
+Alternative to http server:
+1. on install machine nc -l 1234 | sudo bash
+2. On another machine nc INSTALL_MACHINE 1234 <live-kexec
+Obviously beware that anyone on your network could send commands to the install machine.
