  <marlinc_> Hey there, I'm not sure whether I'm running into a bug or not
  <marlinc_> I'm trying to set the password hash for the root user on a system using the chpasswd module
  <marlinc_> It should match new hash at this line in the module but it doens't seem to match
  <marlinc_> https://github.com/cloud-init/cloud-init/blame/master/cloudinit/config/cc_set_passwords.py#L163
  <marlinc_> I can confirm this when running it through https://regex101.com/r/Nj7VTZ/1
  <marlinc_> Then I was thinking, isn't [] for lists of characters rather than lists of strings
  <marlinc_> Changing it to \$(1|2a|2y|5|6)(\$.+){2} does work
  <marlinc_> At least in regex101
  <marlinc_> smoser, you any idea, I saw you commited the change: https://github.com/cloud-init/cloud-init/commit/21632972df034c200578e1fbc121a07f20bb8774
  <smoser> marlinc_: i'd think yes. that is a bug for the '2a' and '2y'
