> Can't you just use dh_link to add a symlink? I am re-evaluating this fix and considering to revert it. The problem with Postfix was that it did not find /usr/include/mysql/mysql.h and we added a symlink in libmariadb-dev to fix it.
However, this symlink already existed in libmariadb-dev-compat, and default-mysqlclient-dev depends on libmariadb-dev-compat, so Postfix should have found it. I wonder why that package was not correctly installed at Postfix's build time.
