8.3.11 Online Update and Delta Packages
Online Update now supports a special kind of RPM package that only stores the binary
difference from a given base package. This technique significantly reduces the package
size and download time at the expense of higher CPU load for reassembling the final
package. See /usr/share/doc/packages/deltarpm/README for technical
details.
8.3.12 Print System Configuration
At the end of the installation (proposal dialog), the ports needed for the print system
must be open in the firewall configuration. Port 631/TCP and port 631/UDP are needed
for CUPS and should not be closed for normal operation. Port 515/TCP (for the old
LPD protocol) and the ports used by Samba must also be open for printing via LPD or
SMB.
8.3.13 Change to X.Org
The change from XFree86 to X.Org is facilitated by compatibility links that enable access
to important files and commands with the old names.
