Hi All,

The master branch on the unionmount-testsuite tree [1] has been updated.

Changes in this update:
- Support user configurable underlying filesystem

So far, unionmount-testsuite used hardcoded paths for layers and
mount point.  Using underlying filesystem other than tmpfs was possible,
but not very easy to setup.

This update brings the ability for user to configure custom paths
with a custom filesystem for the underlying layers.
This is intended to be used for integration with xfstests [2].

Here is an excerpt from the README:
---
  The following environment variables are supported:

  UNIONMOUNT_BASEDIR  - parent dir of all samefs layers (default: /base)
  UNIONMOUNT_LOWERDIR - lower layer path for non samefs (default: /lower)
  UNIONMOUNT_MNTPOINT - mount point for executing tests (default: /mnt)

  When user provides UNIONMOUNT_LOWERDIR:

  1) Path should be an existing directory whose content will be deleted.
  2) Path is assumed to be on a different filesystem than base dir, so
     --samefs setup is not supported.

  When user provides UNIONMOUNT_BASEDIR:

  1) Path should be an existing directory whose content will be deleted.
  2) Upper layer and middle layers will be created under base dir.
  3) If UNIONMOUNT_MNTPOINT is not provided, the overlay mount point will
     be created under base dir.
  4) If UNIONMOUNT_LOWERDIR is not provided, the lower layer dir will be
     created under base dir.
  5) If UNIONMOUNT_LOWERDIR is not provided, the test setup defaults to
     --samefs (i.e. lower and upper layers are on the same base fs).
     However, if --maxfs=<M> is specified, a tmpfs instance will be
     mounted on the lower layer dir that was created under base dir.

Many thanks to Vivek for review and testing.

Thanks,
Amir.
