Hooks
=====

Since version 0.8.1, apt-dater can call hooks before and after doing an
action on a host. Hooks executables are located in:

+---------+---------------------------+
| action  | path                      |
+---------+---------------------------+
| connect | /etc/apt-dater/pre-con.d  |
|         | /etc/apt-dater/post-con.d |
| install | /etc/apt-dater/pre-ins.d  |
|         | /etc/apt-dater/post-ins.d |
| refresh | /etc/apt-dater/pre-ref.d  |
|         | /etc/apt-dater/post-ref.d |
| upgrade | /etc/apt-dater/pre-upg.d  |
|         | /etc/apt-dater/post-upg.d |
+---------+---------------------------+

The executables are run by run-parts(8). The environment contains
