I'll try to post an example soon, but you don't have to split it up into "200
files" to take advantage of autoloading. You would need to split it into "two
dozen directories" though.
On the other hand, you can put everything into site.pp. I'm sure you'll agree
that this is a mistake too. I use modules but I don't split a module's
manifest (init.pp) into different files until the file starts to get large.
For instance, you could put all your classes into /modules/module-name/init.pp.
This works well if all but one or two class are really small. This is what I
do by default because if I put "include cups::client" in site.pp, puppet will
auto import:
/modules/cups/init.pp
/modules/cups/client.pp
/modules/cups/client/init.pp (I think this last one is true, but I
don't know)
I like the different folders because it keeps the files and templates with the
manifests, and t makes it easier to tell which files can safely be deleted.
For me, the key to keeping things easy was to remember that I didn't need to
break a module into more than one file, but I could if they got too big.
