nutch 1.12 - different options for each crawldb

[Jose-Marcio Martins da Cruz]

Hello,
I'm using nutch 1.12/solr to index sites of our organisation, and I'd like to divide them in some different classes, 
e.g. public and private servers.

This works fine with different crawldb databases, each one with its own set of 
seeds.

But I'd like to have different configuration files, e.g., regex-urlfilter.txt, nutch-site.xml, ... or, eventually, have 
one "conf" directory for crawldb

Is it possible and if yes, how can I do this ?

Thanks for your help.

Regards
