fai-make-nfsroot docs and missing reboot

In your template (e.g. /srv/tftp/fai/pxelinux.cfg/DEFAULT.tmpl or 
whereever your tftp root lies) you have to add 'reboot' to your 
'FAI_FLAGS'. My DEFAULT.tmpl looks like this:

<snip>
# generated by fai-chboot for host default with IP no IP
default fai-generated

label fai-generated

kernel vmlinuz-4.19.0-17-amd64
append initrd=initrd.img-4.19.0-17-amd64 ip=dhcp 
root=10.12.0.1:/srv/fai/nfsroot:vers=3 rootovl 
FAI_FLAGS=verbose,sshd,createvt,reboot 
FAI_CONFIG_SRC=nfs://10.12.0.1/srv/fai/config FAI_ACTION=install
</snip>

'sshd' allows me to SSH into the machine during install, with 'createvt' 
I can switch to a dedicated virtual terminal during install and 'reboot' 
instructs FAI to reboot at the end of the installation process instead 
of waiting for someone to press 'enter'.
