[debian-mysql] Bug#602813: /etc/init.d/mysql: init script leaks file descriptors

[Arthur de Jong]

Subject: /etc/init.d/mysql: init script leaks file descriptors
Package: mysql-server-5.1
Version: 5.1.49-2
File: /etc/init.d/mysql
Severity: normal

The /etc/init.d/mysql script leaks file descriptors to
the /usr/bin/mysqld_safe script. This causes problems problems for
unattended-upgrades (see #379645) and is generally considered a bad idea
(can also cause other problems).

It is probably simplest to use start-stop-daemon in the init script.
This closes all file descriptors and redirects to /dev/null (as well as
all kind of other things a daemon should do to correctly background
itself).

Using start-stop-daemon can be done by by replacing:
  /usr/bin/mysqld_safe > /dev/null 2>&1 &
with:
  start-stop-daemon --start --background --quiet --exec /usr/bin/mysqld_safe
in the script.

Thanks.
