[Puppet Users] Does anyone know how to evaluate a node hostname in nodes.pp file?

You might consider letting regex and facter do more of the work for you.

node /^node\d+\.yourdomain\.com$/ {

include $::osfamily # or the more specific $::operatingsystem
}

However if you were to build a case around the node name you can use
$::hostname or $::clientcert. I use clientcert more often because the
hostname is not always correct through provisioning in my system. Same
syntax either way.

node /^fe\d+\.(ord|lax|sfo)\.mydomain\.com/ inherits basenode {

include hostgroup::frontend

case $::clientcert {
/^fe02(.*)/: { # matching any server named fe02
cron::listings { 'listings':
cron_env => 'production_migrate',
cron_user => 'deploy',
}
}
default: {}
}

}

You don't even need that for the OP's original case. Instead of grouping
nodes and then trying to separate them out again, it would make more sense
to avoid grouping them in the first place:

node 'node1.com' {
include 'solaris'
}

node 'node2.com' {
include 'redhat'
}

node 'node3.com' {
include 'aix'
}

# Note: the default case in the OP's pseudocode
# would never have applied, but I infer that something
# like this was desired:
node default {
include 'generic'
}


On the other hand, in direct answer to the OP's question, nodes.pp is a
Puppet manifest just like any other, so you can access node facts there.
Facts are not dependent on node blocks (and indeed, node blocks are
optional). You can access nodes' hostnames via the $::hostname fact.
