I'll also note that it's totally standard for the theregister.com to have headlines that incorporate puns or colloquial language. In this case the original headlines has "slim staff" which is also awkward but has a different mental image :-)
For example - "original meaning" here is kind of strange. What if the original documentation is wrong or ambiguous? Then we don't want the original meaning, we want the intended meaning. But I'll leave it in here as an example.
“Staff must park behind the building”.
I'm not sure of the technical terms, but "staff" can both be the total mass of employees, and the individual employees.
"Small staff" means a small number of employees in the same way "small army" means a small number of soldiers.
Something, something countable vs uncountable nouns?
