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. + + + + Debian Packaging System + + +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: + + + + +/usr (excluding /usr/local) + + + + +/var (you could make +/var/local and be safe in there) + + + + +/bin + + + + +/sbin + + + + +/lib + + + + +For instance, if you replace /usr/bin/perl, that +will work, but then if you upgrade your perl +package, the file you put there will be replaced. Experts can get +around this by putting packages on hold in +aptitude. + + + +One of the best installation methods is apt. You can use the command +line version apt-get or full-screen text version +aptitude. Note apt will also let you merge +main, contrib, and non-free so you can have export-restricted packages +as well as standard versions. + + + + + Application Version Management + + + +Alternative versions of applications are managed by update-alternatives. If +you are maintaining multiple versions of your applications, read the +update-alternatives man page. + + + + + Cron Job Management + + +Any jobs under the purview of the system administrator should be in +/etc, since they are configuration files. If you +have a root cron job for daily, weekly, or monthly runs, put them in +/etc/cron.{daily,weekly,monthly}. These are +invoked from /etc/crontab, and will run in +alphabetic order, which serializes them. + + + +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 /etc/crontab, or, better yet, +/etc/cron.d/whatever. These particular files +also have an extra field that allows you to stipulate the user under +which the cron job runs. + + + +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 +/usr/share/doc/cron/README.Debian. + + + + -- cgit v1.2.3
