You can split it up into whatever files you want. You'll just want to
be careful if you have multiple files that match as the last match
would be what is used. FAI processes the files in the class directory
in shell sorting order.

We also use multiple Perl scripts that perform a regexes on the
hostname and sets classes that way. One script perl per cluster type or
customer.

Cheers,
Andrew

HI, Juri,

I don't see how that works, the hostname is going to end up being the hostname 
of the FAI server, isn't it?

Hello,

Maybe you are looking for something like that:
#! /bin/bash
MYDOMAINNAME=$(hostname -d)
MYFQDN=$(hostname -f)

case $MYFQDN in
  fqdnhost.example.com)
echo "EXAMPLECLASS1" ;;
  *)
echo "FAIBASE DEBIAN DEMO" ;;
esac

case $MYDOMAINNAME in
  mydemodomain2.example.com)
echo -en "DOMCLASS2 "
case $HOSTNAME in
  demohost|client*)
echo "EXAMPLECLASS2" ;;
  *)
echo "FAIBASE DEBIAN DEMO" ;;
esac ;;
  mydemodomain3.example.com)
case $HOSTNAME in
  demohost|client*)
echo "EXAMPLECLASS3" ;;
  *)
echo "FAIBASE DEBIAN DEMO" ;;
esac ;;
esac

Best Regards,

HI,
Same question as in StackOverflow:
Fully Automated Install (FAI) has hosts in the file 50-host-classes. We 
currently have a bunch of hosts which have similar names (eg, 
ba-hostxx.subdomain). The sub-domains are different but one cannot specify 
host.subdomain in the class file as the '.' is invalid.  However it was setup 
originally, it has morphed over time and we have
ba-w6*
ba-w7*
ba-w*
dr1-w4*
dr1-w6*
dr1-w7*
dr1-w*
and so on
Is it possible to have different hosts in different files? Or to specify the 
host in some other fashion than just
hostname*)
echo "BASEFILE FILE" ;;
such as
cluster/hostname*)

echo "BASEFILE FILE" ;;
?
The documentation leads one to the opinion that all hosts sit in the 50- file 
which makes it very unwieldy.

Thanks
