I've just did a fast read on your patch. Nice work that you patched the
documentiotion, too.

But to the patch: Why do you do it in a host atomic way while it might
be less work when doing it on hostgroups?

Sequence like this:

define hostgroup{
hostgroup_name x-linux-hosts
alias template hostgroup for linux hosts
register 0 # we don't want to see it but use it...
}

define service {
hostgroup_name x-linux-hosts # bind to a hostgroup
service_description Disk /
check_command check_disk!/
... other needed stuff ...
}

define host{
host_name a-linux-host
hostgroups x-linux-hosts
... other needed stuff ...
}
define host{
host_name n-linux-host
hostgroups x-linux-hosts
... other needed stuff ...
}

With something like this you control over the group membership which
services should be checked on a host.

Benefit:
Onetime service definitions
Onetime hostgroup defs
easy going after a little brainpower what service might be a standard
service in your environment.

Hendrik
