Bug#923644: release-notes: Semantic for using environment variables for su changed



Package: release-notes
Severity: normal
Tags: patch

Su works no differently in repect to environment variables than it did
in the previous stable version. Please include a text like the
following.

Su changed semantik in Buster and no longer copies over DISPLAY
and XAUTHORITY environment variables. You need to explicitly set them
and allow explicitly access to your display if you need to run
graphical applications with su. See Bug #905409 for an extensive
discussion.
