Replace binaries and Files with dpkg-divert

Submitted by srlinuxx on Thursday 14th of December 2006 03:22:15 PM Filed under

HowTos

File `diversions’ are a way of forcing dpkg not to install a file into its location, but to a `diverted’ location. Diversions can be used through the Debian package scripts to move a file away when it causes a conflict. System administrators can also use it to override some package’s configuration file, or whenever some files (which aren’t marked as ‘conffiles’) need to be preserved by dpkg, when installing a newer version of a package which contains those files.

dpkg-divert is the utility used to set up and update the list of diversions. It functions in three basic modes - adding, removing, and listing diversions. The options are –add, –remove, and –list, respectively. Additionally, it can print out the real name for a diverted file. Other options (listed below) may also be specified.

The dpkg-divert command allows you to replace a binary installed upon the system, and have this replacement persist even if you upgrade packages.This is very useful if you want to use an updated version of some application instead of old version existing on your machine.

Witcher 2 Bug Prompts Linux Creator To Recommend Devs Play Steam Games

It’s common for NVIDIA and AMD to tweak their drivers to optimise specific titles, but patches to operating systems just for games? Usually developers work around platform quirks, but that’s not good enough for Linus Torvalds, the man behind Linux. When crashes in The Witcher 2 were caused by Linux’s core software, Torvalds not only requested the bug be fixed, but that Steam games should be used in the future as “good tests of odd behaviour”.

‘Enterprise customers are now more willing to implement open source’

Jim Whitehurst expects India to play a larger role in NYSE-listed Red Hat’s global strategy, thanks to the rapid pace of infrastructure creation. “When a new system’s put into place, it’s increasingly likely that it may be built on open source. We like places where there is a lot of infrastructure going in,” Whitehurst, President and Chief Executive Officer, Red Hat, said. Red Hat is the world’s largest commercial distributor of the open source-based Linux operating system. Open source denotes software for which the original source code is made freely available and may be redistributed and modified. In an interaction with BusinessLine, Whitehurst throws light on the opportunities in the Indian marketplace for open source. He also explains why the company is keen to increasingly move more support functions to India.

The Navy's Newest Linux-Powered Command Center Is Right Out Of Star Trek

The DDG-1000 Zumwalt Class Destroyer could very well revolutionize the way the Navy does its surface warfare business. One of its biggest innovations is ditching the cramped, darkly lit Combat Information Center (CIC), a fixture for many decades on past USN combat ships, and replacing it with the state-of-the-art, spacious, Star Trek bridge-like Ship's Mission Center.
