Wes,
Not very elegant, but you could define a list in the order you want and iterate
over that instead of getting the indices from the array:
"dns_idx" slist => { "0", "1", "2" };
You could also make the servers an slist instead of an array, for example:
"siteconf" slist => { "10.9.72.50", "10.18.30.50", "10.32.28.30" };
and then iterate over that slist to insert the lines. If you really need the
comment about each server, you could store them in an array indexed by the
server's IP address.
On the other hand, in this particular case, do you really care about the order?
DNS servers should in principle be exchangeable, and in a large organization
it's even good practice to have machines go to different servers as their first
choice, to spread the load.
Also, unless you are using empty_file_before_editing in your file-edit
promises, the missing lines in the file will be inserted when needed, which may
break the order in any case, if some other lines were already there.
Best regards,
