-Without HOST TYPE, disable pxe server and fai server.
-TYPE is one of arch, plain, fai.
-HOST is a hostname known to the dhcp server, or default for all
-Note, when switching between plain and arch, you will need to
+HOST Only do dhcp pxe for HOST. The hostname must be known to the dhcp
+ server to target its mac. Use "default" for all hosts.
+ Required in fsf office environment.
+
+TYPE One of arch, parabola, plain, fai.
+
+-a Don't setup pxe, just Wait for 2 dhcp acks, then disable the pxe
+ server after a delay. First ack is for pxe boot, 2nd ack is
+ for os boot. Sometimes on debian, there is a 3rd one shortly
+ after the 2nd. I can't remember exactly why this caused a
+ problem, but I'm hoping the sleep will take care of it.
+-d Don't alter dhcp config. Only make sense for fai type, and on network
+ other than home or fsf, when using fai-cd, or pxe-kexec.
+-k Pass -k to myfai-chboot.
+--no-r Pass --no-r to myfai-chboot.
+-r Don't redeploy fai config. For example, if there is a different host
+ that is mid-install.
+
+-S sets FAI_ACTION=sysinfo, see myfai-chboot for more info.
+-w Setup pxe, then wait like -a.
