Using APT to keep DeadRat 9 up to date.

Here's a slightly out of date HOW-TO I wrote that has kept me somewhat sane when using RedHat 9 (DeadRat):

Keeping your RH9 box up to date with apt

Apt, normally a base part of the debian Linux distrobution has been ported
to RedHat and rpm. Apt makes it extremely easy to keep up to date with the
latest fixes and packages from the official RedHat distribution. Apt also
does all the dependancy checking for you. Thus keeping your installation
sane as well as up to date. It will not let you install incompatible package

- Start here:

- download the apt for RedHat 9 package.

- install the apt for RedHat 9 package:

rpm -Uhv apt-0.5.5cnc5-fr2.i386.rpm

- update the package list:

apt-get update

You can 'cron' this command if you like. Use the really quiet mode to
prevent email unless there's an error. 'apt-get -qq update'

- upgrade your installed packages:

apt-get upgrade

You can also 'cron' this command. I prefer to use the 'download' only
switch. This way I get a email report from std out about the packages
that are ready to be updated. I can then manually do a 'apt-get update'
at my convienance and resolve conflicts if they occur.

download only mode: 'apt-get -y -q -d upgrade'

- erase old 'out of date' packages from the local cache"

apt-get autoclean

You should cron this one, for a once a week operation.

- installing new packages and their dependancies via apt:

You have to know the package name first:

browse http://ayo.freshrpms.net/redhat/9/i386/ to find the packages available.
(this pointer is stored in /etc/apt/sources.list and may update/change)

Once you find the package you want, install it.

apt-get install vim-X11

You don't need to specify the version, or the file name.

- checking on dependancies for available packages:

You can see the dependancy and package descriptions for packages in the
local cache:

apt-cache showpkg vim-X11

Use this command to decide if it's worth installing, investigating what
you're missing, etc..
