Comment 10 for bug 1727358

You can grep through, the onlyi real function taht uses it is 'rand_str'. and i'm not sure really why that would be called at the point that you're seeing the slow down.

I think it more valuable for you to figure out why your environment is causing this issue and fixing that rather than fixing cloud-init (and subsequently all users of entropy).

Also, information about how you've come across this bug would be good.
