That's great, and the code grants you explicit permission (via the
ASF-2 license) to copy and redistribute it, in whole or in part. The
permission is conditional on you also doing these:

* give all recipients a copy of the ASF-2 license text (as in the
  ‘python-daemon’ code base);

* make clear in the work that it is derived from ‘python-daemon’;

* retain the copyright notices for the parts of the work you include.

So, you have full permission to copy the parts as you have done, but
you need to follow the ASF-2 copyright license terms when you do.

Regardless, you only have permission to copy parts of a work for this
purpose by following the license terms.

Changing the license terms isn't permitted, the ASF-2 license applies
to the parts of the work you've got from ‘python-daemon’. You're free
to make a derived work, as you've done, under those terms :-)

Thanks for understanding and respecting the copyright of the authors.
