I'm trying to enable some automated testing of Boost libraries.
In the past I've invoked b2 in the status directory, but would like to move to using  run.py
With python 2.7.12  and git 2.7.4 on Ubuntu

python run.py --runner test_it_all --toolset=gcc --tag=develop

File "/doc/boost/test/boost_regression_src/regression.py", line 286, in __init__
    self.main()
  File "/doc/boost/test/boost_regression_src/regression.py", line 623, in main
    getattr(self,action_m)()
  File "/doc/boost/test/boost_regression_src/regression.py", line 577, in command_regression
    self.command_cleanup()
  File "/doc/boost/test/boost_regression_src/regression.py", line 295, in command_cleanup
    self.git_source_checkout(True)
  File "/doc/boost/test/boost_regression_src/regression.py", line 875, in git_source_checkout
    self.git_checkout(git_info['boost'], self.git_branch(), clean)
  File "/doc/boost/test/boost_regression_src/regression.py", line 846, in git_checkout
    self.git_command( 'submodule foreach', 'git submodule deinit .')
 File "/doc/boost/test/boost_regression_src/regression.py", line 834, in git_command
    raise Exception( 'GIT command "%s" failed with code %d' % (git_cli, rc) )
Exception: GIT command "git submodule foreach "git submodule deinit ."" failed with code 256

Any suggestions on how to resolve this ?
