/etc/init.d
script seems to be sourcing an
/etc/default/
file without checking for its existence first.
Files in /etc/default/
can be deleted by the administrator at
any time, and init scripts are required to handle the situation
gracefully. For example:
.
[ -r /etc/default/foo ] && . /etc/default/foo
