Hello Matthew,

Thanks for the advise, this is what I am trying to archive, as I am 
using make.conf exactly to primarily  point to another src.conf and 
src-env.conf (shortend, the full version is in another reply):
#

MAKE_SHELL?=sh

SRCCONF=/data/admin/build/vbox/src.conf
SRC_ENV_CONF=/data/admin/build/vbox/src-env.conf

Basically I want all three {make,src,src-env}.conf to reside within the 
same folder (that is not /etc), one for each host this machine is 
buiding base for.

However, it seems, my src-env.conf is not being honored, not sure about 
the contents of src.conf.
