hello list,

i wanted feed all needed Options to module os\_server via a Lookup plugin.  
this way i would be able to out every logic we need in on plugin.

but as i understand this feature is deprecated.

I can use the lookup for every value of a param, but then i need a task for every combination of params that we use in our environment, with the normal problem that i need to alter every task wen we have some basic change.  
And something like ‘meta:’ is different for any type of server?

does anybody have some idea to tackle this problem?

Thanks in advanced  
Mark
