Even if you're +familiar with Linux in other distributions, there are things you +should know about Debian to help you to keep your system in a good, +clean state. This chapter contains material to help you get oriented; +it is not intended to be a tutorial for how to use Debian, but just a +very brief glimpse of the system for the very rushed. + +</para> + + <sect2><title>Debian Packaging System</title> +<para> + +The most important concept to grasp is the Debian packaging system. +In essence, large parts of your system should be considered under the +control of the packaging system. These include: + +<itemizedlist> +<listitem><para> + +<filename>/usr</filename> (excluding <filename>/usr/local</filename>) + +</para></listitem> +<listitem><para> + +<filename>/var</filename> (you could make +<filename>/var/local</filename> and be safe in there) + +</para></listitem> +<listitem><para> + +<filename>/bin</filename> + +</para></listitem> +<listitem><para> + +<filename>/sbin</filename> + +</para></listitem> +<listitem><para> + +<filename>/lib</filename> + +</para></listitem> +</itemizedlist> + +For instance, if you replace <filename>/usr/bin/perl</filename>, that +will work, but then if you upgrade your <classname>perl</classname> +package, the file you put there will be replaced. Experts can get +around this by putting packages on <quote>hold</quote> in +<command>aptitude</command>. + +</para><para> + +One of the best installation methods is apt. You can use the command +line version <command>apt-get</command> or full-screen text version +<application>aptitude</application>. Note apt will also let you merge +main, contrib, and non-free so you can have export-restricted packages +as well as standard versions. + +</para> + </sect2> + + <sect2><title>Application Version Management</title> +<para> + + +Alternative versions of applications are managed by update-alternatives. If +you are maintaining multiple versions of your applications, read the +update-alternatives man page. + +</para> + </sect2> + + <sect2><title>Cron Job Management</title> +<para> + +Any jobs under the purview of the system administrator should be in +<filename>/etc</filename>, since they are configuration files. If you +have a root cron job for daily, weekly, or monthly runs, put them in +<filename>/etc/cron.{daily,weekly,monthly}</filename>. These are +invoked from <filename>/etc/crontab</filename>, and will run in +alphabetic order, which serializes them. + +</para><para> + +On the other hand, if you have a cron job that (a) needs to run as a +special user, or (b) needs to run at a special time or frequency, you +can use either <filename>/etc/crontab</filename>, or, better yet, +<filename>/etc/cron.d/whatever</filename>. These particular files +also have an extra field that allows you to stipulate the user under +which the cron job runs. + +</para><para> + +In either case, you just edit the files and cron will notice them +automatically. There is no need to run a special command. For more +information see cron(8), crontab(5), and +<filename>/usr/share/doc/cron/README.Debian</filename>. + +</para> + </sect2> + </sect1> |
