 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.
+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.
+
+This has been tested on trisquel 7 & 8 & ubuntu 16.04 & 18.10.  With
+18.10 and trisquel 8 on an x200, kexec was unreliable, resulting in
+freezes and kernel panics.
 
 If the screen just sits in a weird color inverted, corrupted looking state,
 it's probably nothing wrong with the computer, but a problem
