This makes our list definitions mergeable with custom list values
set by users.
Previously, a module error ("value is a string while a list
was expected") was thrown instead.
This commit was partly auto-generated with this script:
#!/usr/bin/env ruby
Dir["**/*.nix"].each do |file|
src = File.read(file)
fixed = src.gsub(/ReadWritePaths *= *(.*?);/) do
"ReadWritePaths = [ #{$1} ];"
end
File.write(file, fixed) if fixed != src
end
