The problem here is that the block passed to 'setcode' isn't run until
later, at which point $6 is set to the last user's homedir. Try this:
Facter.add("...") do
homedir = $6 # dereference immediately
setcode { homedir }
end
This works because 'homedir' is local to each fact definition, whereas
$6 is global. At least, it *should* work. :)
Yes, I know you already found a solution, but this is more a ruby
question than a Puppet/Facter question, and I figure it's worth
pointing out the correct solution.
