I use a similar approach, which I will include because I think it might
be easier to understand.

I use a centralized host for DNS configuration files, if one of them
changes I need to copy it, then depending on the destination server 
run one or two set of commands in a specific order.

On our master server I need to generate/update the reverse zones.
On our all servers I need to tell named to re-read it's configs and zones

        AddInstallable = (
                named_needs_reload # define this class if a file is changed
                )

        dnsmaster       = ( dnsmaster )
        named_owner     = ( owner )
        named_group     = ( group )



actionsequence = (
                # shellcommands is defined in another file and will also run
                shellcommands.firstpass  # run and define temporary class 
firstpass
