Title:
  Change breaks cloud-init on Ali

Status in cloud-init:
  Fix Released

Bug description:
  Hi,

  cloud-init change

  https://github.com/canonical/cloud-
  init/commit/70dbccbbb27f7cc3f2decd692d41403f0d745c62

  appears to break cloud-init on Aliyun. We had been using a version
  20.2 or more precisely

  http://ftp.de.debian.org/debian/pool/main/c/cloud-init/cloud-
  init_20.2-2~deb10u1_all.deb

  with no issues. Version 20.4.1 or more precisely

  http://ftp.de.debian.org/debian/pool/main/c/cloud-init/cloud-
  init_20.4.1-1_all.deb

  breaks with the log output shown below. As the key device-number is
  not used in 20.2 this clearly points to the change referenced above.
  It is kind of unclear where that key is supposed to be configured as
  there is no other reference to that in the code.

  This is more or less a standard Debian configuration that we are using from the packages referenced above. This appears to cause user and group management to be skipped which is causing us headache. Quite interestingly
  it does work find on AWS which appears to use the same code.

  Let me know if you need anything else.
