I wrote a "memorysize_mb" fact to solve this problem; this ensures the number returned is only an integer value.
$ cat memorysize_mb.rb
require 'facter'
Facter.add("memorysize_mb") do
confine :kernel => :Linux
ram = 0
# Steal linux's meminfo
File.open( "/proc/meminfo" , 'r' ) do |f|
f.grep( /^MemTotal:/ ) { |mem|
ram = mem.split( / +/ )[1].to_i / 1024
}
end
setcode do
ram
end
end
