Hi Jeff,

Are you perhaps using "su" (instead of "su -") when changing to root?
If so, then there is a Stretch -> Buster specific change specifically
for "su" about that in util-linux's NEWS file.  It will probably be
written in the release-notes for buster (once we start writing those for
buster).

I can recommend using "apt-listchanges", which will show the NEWS files
of packages on upgrades.

Thanks,
