Status in open-vm-tools source package in Bionic:

Bug description:
  Using open-vm-tools/xenial,now 2:10.2.0-3ubuntu0.16.04.1~ppa6 amd64
  [installed], subprocesses started by vim.vm.guest.ProcessManager fail
  to create temporary files.

  Summary:
  * When running subprocesss through open-vm-tools 2:10.2.0-3ubuntu0.16.04.1 (via vim.vm.guest.ProcessManager), subprocesses crash while trying to write temporary files.
  * Subprocesses run correctly when executed directly from the shell
  * Subprocesses execute correctly from open-vm-tools open-vm-tools-10.2.0-7253323, when compiled from source

  Steps to reproduce:
  1. Install open-vm-tools/xenial 2:10.2.0-3ubuntu0.16.04.1~ppa6 on a VMWare ESX 6.5 16.04 guest
  2. Using VMOMI API, start a child process that relies on temporary files (eg. `apt-get update`)
  3. Note the error code on the child process (eg. 100)
  4. Run process directly from guest shell (eg. `apt-get update`)
  5. Note the successful return code on the child process (1)

  Logs from vmtoolsd on guest:
