Red Hat extends the FHS structure slightly to accommodate special
files used by Red Hat Linux.
Most files pertaining to the Red Hat Package Manager
(RPM) are kept in the
/var/lib/rpm/ directory. For more information on
RPM see the chapter titled Package Management with
RPM in the Official Red Hat Linux Customization Guide.
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
the Section called Sysconfig Information in Chapter 3 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.
