RFC: Classes list for FAI/Lenny

The Etch installation scheme with our FAI server used one class for each type of node (NODE_COMPUTE, STORAGE, ...) but this is somehow inflexible when a mixture of classes is needed and also quite error-prone in terms of duplicated package lists. Thus, I propose to move to a modular FAI class concept, where in the end a larger number of dedicated classes compose the final class.

Service Classes

This is a sample list of possible class names:

Class nameSorted ascending purpose / packages in this class (example)
ARECA_4DISK_750GB_RAID6 perform any necessary actions for creating a 4 disk RAID6 array with 750 GB disks on a ARECA controller
ATLAS_CONDOR_MASTER master node for Condor
ATLAS_CONDOR_NODE Condor compute node
ATLAS_CONDOR_SUBMIT submission only head nodes (remote submission) - if needed
ATLAS_MAIL_CLIENT set-up this machine as a forward only mail client
ATLAS_MAIL_SERVER everything about mail server in the Atlas framework
ATLAS_NIS_CLIENT set-up for Atlas NIS clients
ATLAS_NIS_SERVER set-up for our Atlas NIS server
DEFAULT bare minimum list needed everywhere (vim, emacs, apt-file, htop, sysstat, iostat, ...)
DEVEL install development packages (man pages, compilers, debugging tool, ...)
EXPOSED this host is exposed and needs, iptables, apticron, security.debian.org,...
hostname remember that the class hostname is always available
LDG install LDG related things (ldg-server/client)?
LSC lscsoft related stuff
MATLAB_BATCH install only matalb stuff for compute nodes
MATLAB_INTERACTIVE install interactive matlab environment
SQL_MYSQL install mysql server
SQL_POSTGRESQL install postgresql server
WEBSERVER install and configure basic apache

I guess many more classes are possible, but you get the idea.

Host Classes

Unless FAI has its own way of creating dependency between classes, we probably need to write a wrapper script which maps a host class to service classes, e.g.
