Chapter 1. File System Structure

The

/var/spool/up2date/

directory contains files used by Red Hat Update Agent, including

RPM header information for the system. This location may also be used to temporarily store RPMs

downloaded while updating your system. For more information on Red Hat Network, see the Red Hat

Network website at https://rhn.redhat.com/.

Another location specific to Red Hat Linux is the

/etc/sysconfig/

directory. This directory stores

a variety of configuration information. Many scripts that run at boot time use the files in this directory.

See Section 3.7 for more information on what is within this directory and the role these files play in

the boot process.

Finally, one more directory worth noting is the

/initrd/

directory. It is empty, but is used as a critical

mount point during the boot process.

Warning

Do not remove the /initrd/ directory for any reason. Removing this directory will cause your system

to fail to boot with a kernel panic error message.
