if you're reading this, it's most likely because you had replaced /var/lib/mysql
94
with a symlink, then upgraded to a new version of mysql, and then dpkg
95
removed your symlink (see #182747 and others). the mysql packages noticed
96
that this happened, and as a workaround have restored it. however, because
97
/var/lib/mysql seems to have been re-created in the meantime, and because
98
we don't want to rm -rf something we don't know as much about, we're going
99
to leave this unexpected directory here. if your database looks normal,

and this is not a symlink to your database, you should be able to blow
