Certification Summary

 < Day Day Up > 

You can have great control over how your Linux installation is set up and configured. You can control almost all aspects of the user environment, as well as the details of your kernel. Any variables or system-wide functions you may need to run can be kept in the /etc/bashrc or /etc/profile script.

You can set up quotas to limit the user's disk usage. You can set up one quota per partition, and set soft and hard limits for users. With grace periods, you can set up a soft limit to give users an appropriate warning.

The easiest way to update a kernel is to install (and not upgrade it) from a Red Hat RPM. When you do, it automatically updates your boot loader files as needed.

Alternatively, the kernel can be optimized for your particular installation and hardware, and you have detailed control over its configuration. To make a modular kernel, you need to run six commands: make mrproper, make config, make dep, make clean, make modules, make modules_install and make install. If you are compiling a monolithic kernel, you will not need to run the last two module-related commands.

The cron and at daemons allow you to schedule jobs to run at any given time.
