PFAI is able to do this task; we use it in a cluster of currently 113 machines exactly for this purpose; this setup runs for nearly two years now. most of PFAI is already included in FAI, currently I am preparing some patches for thomas lange to merge the rest of my extensions into FAI.
basic idea: every administrator has rw access to a cvs repository (our core team consists of 5 people), where the configuration data is stored. each client does a checkout of this central repository on installation time and updates its checked out copy when a call-for-update is issued (we broadcast these using a prepared ssh key for root). the machine logs the differences as told by cvs into a file cvs.log. then a nearly normal FAI installation is done, of cause without doing the harddisk partitioning and mkfs, feeding cvs.log into a special mechanism of fcopy. I wanted to prepare a talk on this for Debian @ LinuxTag, but this was refused for the "big" rooms. If there are some people interested in this, I'll prepare it anyway and use one of the small rooms (for about 50 people) they offer. -- c u henning
