Yep ;D
The bootstrap (/usr/local/etc/rc.d/dev_bootstrap.sh) works right now.
Still got a (non significant ??) error when ending the bsdinstaller :
…pkg_create: make_dist: tar command failed with code 256
Creating package /home/pfsense/tools/builder_scripts/conf/packages
Registering depends:.
Creating gzip'd tar ball in '/home/pfsense/tools/builder_scripts/conf/packages.tgz'
*** Error code 1Stop in /usr/ports/sysutils/bsdinstaller.

....
but I think I saw this one before - it doesn't stop from building valids …. builds :)
Thanks for the tip.
