Thank you Sebastian for the advice. Actually, in my case, imaging (not installing) can be a solution.
I just need specific values for each hostgroup (like specific site parameters) or for each host (for chaning the ip address, hostname…).
But as I know, it can’t be done with Fog for now, because there is no linux client yet.
I already found the FAI project, but i can’t deal with remote sites with this solution. If you know other projects, please let me know!
Anyway, thank you very much for your help and for the amazing job you’ve done on the FOG Project!
EDIT: I found here that we can execute post-deploy script with environment variable. It can be a solution, but i can’t find any documentation on the subject. Any help?
