NixOS is not supported by upstream cloud-init. Please contact your
distro maintainers for a fix.

Regarding ISC's client support, this is a real issue and plans for a
replacement are under way.

Title:
  dhcp lookups depend on end-of-life dhclient

Status in cloud-init:
  Invalid

Bug description:
  When using DataSourceHetzner, there is a required dhcp lookup. This
  digs down to a function named `maybe_perform_dhcp_discovery` which
  breaks when a `which dhclient` does not return a binary. This raises a
  `NoDHCPLeaseMissingDhclientError`.

  I have only tested this under NixOS, as its one of the first
  distributions to have have removed `dhclient` from its the package
  tree following the deprecation by ISC's to the package.

  DHCP lookups should be changed to support a non-deprecated dhcp
  library.
