[debian-mysql] Bug#767597: Bug#767597: Bug#767597: mariadb-server-10.0: piuparts / Package purging left files on system

[Otto Kekäläinen]

More information:

In the files (mariadb/mysql)-server.X.X.postrm there is a section that
does the removal and it looks like this:

#
# - Do NOT purge logs or data if another mysql-sever* package is
installed (#307473)
# - Remove the mysql user only after all his owned files are purged.
#
if [ "$1" = "purge" -a ! \( -x /usr/sbin/mysqld -o -L /usr/sbin/mysqld
\) ]; then
  # we remove the mysql user only after all his owned files are purged
  rm -f /var/log/mysql.{log,err}{,.0,.[1234567].gz}
  rm -rf /var/log/mysql

  db_input high mysql-server-10.0/postrm_remove_databases || true
  db_go || true
  db_get mysql-server-10.0/postrm_remove_databases || true
  if [ "$RET" = "true" ]; then
    # never remove the debian.cnf when the databases are still existing
    # else we ran into big trouble on the next install!
    rm -f /etc/mysql/debian.cnf
    rm -rf /var/lib/mysql
    rm -rf /var/run/mysqld # this directory is created by the init
script, don't leave behind
    userdel mysql || true
  fi

fi


Should this perhaps be re-written in some way?
