Module commit

This module contains the functions to implement the commit procedures as part of building an ostree container image. https://github.com/ostreedev/ostree-rs-ext/issues/159

Functions

• prepare_ostree_commit_in
  Given a root filesystem, clean out empty directories and warn about files in /var. /run, /tmp, and /var/tmp have their contents recursively cleaned.
• prepare_ostree_commit_in_nonstrict
  Like prepare_ostree_commit_in but only emits warnings about unsupported files in /var and will not error.
