fai-make-nfsroot docs and missing reboot

Hello all.

FAI noob here, please be patient :)

Reading man page for fai-make-nfsroot it seems 'FULL' install is the 
default. But after having troubles adding Salt repository (could not 
verify server certificate), I noticed that ca-certificates (installed 
only in FULL nfsroot) was not present. After using
fai-make-nfsroot -k -c FULL
it works. That makes me suspect that the actual default is -s .
Could the man page be improved by specifying which is the case?

Moreover, at the end of the install, after saying there were no errors, 
FAI asked to press ENTER to reboot, but IIUC that should me automatic, 
w/o manual confirmation: docs at 
https://fai-project.org/fai-guide/#_a_id_faiflags_a_fai_flags says that 
"If no errors occurred, the client will always reboot automatically." 
and that seems not to be the case (but it's exactly what I wanted: no 
error = boot into newly installed SO w/o any interaction, while 
specifying 'reboot' seems to suggest that it reboots also in case of 
errors).

Tks.
