[rancid] FS switches

It's not the same as the Dell NOS, but I recall hearing that it shares some lineage in the distant, dusty past.  (Well, as dusty as something that's only existed for <10yrs can be, anyway.)  So it makes sense it would be quite similar.  I've installed them for customers, but don't have any here to test with.

NOTE: different FS.com switch product lines use different OSes.  Not sure how different, but definitely not a unified software for all products.  (Again, this makes sense, it's all just vendor reference designs with the FS.com logo slapped onto it.)

       ^^ typo?  that will not be included in the collect, obviously.

Does their O/S have a name?

This would trim all the blank lines in the config.  dell nos does not appear
to output blank lines.
