Well, it works fine, almost out of the box. As dhclient-perl also 
defines an "fai_config_src" variable, I have declared it both in 
dhcpd.conf and dhclient-fai.conf, and FAI_CONFIG_SRC is now set to the 
appropriate value after a PXE boot.

In dhcpd.conf, in general options:
option fai_config_src code 170 = text;
and then for each subnet:
option fai_config_src 
"nfs://subnet-faiserver/usr/local/share/fai/config";  # FAI_CONFIG_SRC

In dhclient-fai.conf:
option fai_config_src code 170 = text;
and add fai_config_src to the request list

And in dhclient-perl, also added fai_config_src to @list.

Surprisingly enough, my 2 year-old questionnaire is out-of-date :-) ; I 
will do so pretty soon.

Thanks for your help,
