sudo resource does not check if command aliases are already in use #8763

The sudo resource (as of chef-client 14.4.56) does not check whether a command alias is already defined before adding it to a file within sudoers.d. This will cause sudo to break, unable to parse the sudoers config.

Chef Version


Platform Version


Replication Case

  1. Create a sudo resource in a recipe which defines some command alias along with the user who should run it
  2. Make a separate file in sudoers.d which contains the identical Cmnd_Alias to what chef-client will produce in its sudoers.d file
  3. Run chef-client
  4. Attempt to sudo will fail, as the Cmnd_Alias is duplicated in two files
