Applications and bundled libraries

Package installation for Linux distributions has traditionally separated libraries and application binaries into different packages, so that only one version of a library would be installed and it would be shared by applications that use it. Other operating systems (e.g. Windows, MacOS X) often bundle a particular version of a library with each application, which can lead to many copies and versions of the same library co-existing on the system. While each model has its advocates, the Linux method is seen by many as superior because a security fix in a particular commonly-used library doesn't require updating multiple different applications—not to mention the space savings. But, it would seem that both Mozilla and Google may be causing distributions to switch to library-bundling mode in order to support the Firefox and Chromium web browsers.
