Ok, Seth, I found that I can see this in a VM when using the original
Trusty release desktop 64bit ISO:

- boot into "Try Ubuntu"
- open a terminal (uxterm works best for me due to this stupid gfx bugs with Cirrus)
- ls /tmp (contains some files already)
- sudo apt-get update
- sudo apt-get install libc6
- ls /tmp (files are gone)

This does *not* happen using the 14.04.2 ISO with the 3.16 kernel.
Interesting is that on the live-cd /tmp is a tmpfs mount, so that would
rather not make overlayfs a suspect.

@Larry, can you post here which kernel version is used in the curtin
environment you are looking at? Did not see that info, yet. Maybe I
missed it. Right now its hard to say which other package versions might
be interesting.

For libc it seems 2.19-0ubuntu6.3 -> 2.19-0ubuntu6.6 for curtin. On the
14.04.2 ISO its from 2.19-0ubuntu6.5 to the same (cannot say yet whether
that is of importance).

Title:
  installing or upgrading libc6 in Trusty removes all content from /tmp
  directory

Status in eglibc package in Ubuntu:
  Invalid
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  We are seeing an issue with installation of dkms package during a
  curtin installation which ends up with /tmp directory being wiped
  clean. This is very bad for curtin as it saves critical installation
  files in /tmp.

  It turns out that it's the of upgrading libc6, which is triggered as a
  result of installing dependencies, that removes content of /tmp. For
  example, installation of gcc results in the same result since it ends
  up with libc6 being upgraded. The only way that this won't be
  recreated is if the latest libc6 is already installed.

  This problem does not exist in precise. It can also be recreated by
  installing the .deb file for any version in trusty including 2.17.
