You explained the problem and gave us a reasonable solution for it.
Thanks for that.

As Marvin sad, your solution is distribution specific. So you could try
to send your fix to the package maintainers of Ubuntu or Debian (it's
most likely that Ubuntu reuses the Debian package without modification).
For the Debian package you can report it here:

Yes, the solution is easy but I guess Chen spent several ours finding
the correct solution (as he explained, he tried different methods).
A note in the documentation or somewhere else could be helpful.
