[Planetlab-devel] node groups & conf files

[Faiyaz Ahmed]

Hi Marc,

Although CfEngine does copy files, it's main purpose is to administer a 
large group of machines autonomously using a cfengine-centric scripting 
language.

The development effort involved, in my opinion, is larger than than of 
maintaining the current conf_files mechanism.  I don't see where 
conf_files is lacking if all you need is a file transfer mechanism with 
post/pre install procedures.

What about conf_files do you not like/ not understand?
