cron-apt for Debian
-------------------
Edit /etc/cron-apt/config
and add rules to
/etc/cron-apt/action.d
You can also add extra configuration for each action (same syntax as
/etc/cron-apt/config) by naming the file /etc/cron-apt/config.d/<actionname>.
The configuration from one action is kept to the next action as well.
The configuration in /etc/cron-apt/config (and config.d/<actionname> consist
of a couple of variables that you can set. They are documented in the config
file itself. The configuration files will always allow any POSIX /bin/sh
compatible syntax so you can use them for hooks and simlar things as well as
simply setting variables.
If you want this tool to be run even if you do not have it up at
04 in the morning you can create a symbolic link from /etc/cron.daily/cron-apt
to /usr/sbin/cron-apt. It will then be run every day (even if the computer is
not on at that time). Similar things can be done for each week, and so on.
You have to have anacron installed for this to work. If not, daily scripts
run 6 AM by crond.
ln -s /usr/sbin/cron-apt /etc/cron.daily/cron-apt
Observe that it is not always a good thing to update package information
and download files when the computer is started. This is especially true
if you do not have a good Internet connection.
You also need to disable the normal cron.d/cron-apt file if you do not want
it to be run twice.
Alternate sources.list file
---------------------------
If you just want to update security related things you can always use an
alternate sources.list files by giving this extra information to the OPTIONS
variable in the configuration file.
OPTIONS="-o quiet=1 -o Dir::Etc::SourceList=/etc/apt/security.sources.list -o Dir::Etc::SourceParts=\"/dev/null\""
Alternatively you can use a separate APT configuration file as described
in the chapter below. You can for example point to a source list as follows:
Dir::Etc::SourceList "/etc/apt/security.sources.list";
Dir::Etc::SourceParts "/dev/null"
Alternate APT main configuration
--------------------------------
There are cases when you need the APT configuration for use with cron-apt to
differ substantially from your standard configuration. For example, cron-apt
will not work with the default configuration of APT, when apt-listbugs is
installed, because this adds a hook that expects keyboard interactivity.
Unfortunately, the apt-tools do not accept Dir::Etc::Main and Dir::Etc::Parts
settings on the command-line. In order to use different paths for them, you
have to create another APT configuration file containing eg:
Dir::Etc::Main "cron.apt.conf";
Dir::Etc::Parts "cron.apt.conf.d";
Then uncomment the following line in your cron-apt configuration file and
point it to your newly created APT configuration file:
export APT_CONFIG=/etc/apt/cron.apt.paths
Don't forget additional options you might have set in /etc/apt/apt.conf since
this file is no longer use when APT_CONFIG point to another conf file.
