Figure 2-25. Retrieval/Installation Settings
The following package retrieval options can be selected (see Figure 2-25):
•
Do not install packages after retrieval
— download selected RPM packages to desired directory
and ignore the installation preferences
•
Do not upgrade packages when local configuration file has been modified
— if the configuration
file has been modified for a package such as
apache
or
squid
, do not attemp to upgrade it. This
option is useful if you are installing custom RPMs on your system and you do not want them
updated or reverted to the default Red Hat Linux packages.
•
Retrieve source RPM along with binary package
— download both the source (
*.src.rpm
)
and the binary (
*.[architecture].rpm
) files
The following installation options are configurable (see Figure 2-25):
•
Use GPG to verify package integrity
— before installing the packages, verify Red Hat’s GPG
signature (highly recommended for security reasons)
•
After installation, keep binary packages on disk
— save binary packages in desired directory
instead of deleting them after installation
•
Enable RPM rollbacks
— allow "undo" of updates. This requires additional storage space.
The following additional options are configurable from this tab:
•
Override version stored in System Profile
— override the Red Hat Linux version in your System
Profile
•
Package storage directory
— change the directory where packages are downloaded; the default
location is
/var/spool/up2date
2.4.1.3. Package Exceptions Settings
The
Package Exceptions
tab allows you to define which packages to exclude from the list of updated
RPM packages according to the package name or file name (see Figure 2-26).
