To maintain the source code, the svn update command can simply be run from the path of the system source. As time goes on, there should be a large number of mirrors available to use. There are currently three mirrors serving up content that provide some redundancy for getting access to code. subversion allows for additional protocols to be used to check out source code (svn, http, https, rsync).
With subversion, the code can be checked out from a URL and then maintained by way of the application. Users of cvsup and csup will remember how some configuration was required to pull in the appropriate pieces of code down from various mirrors for a specific release of FreeBSD (examples include src-all, ports-all, etc.).
#SUBVERSION PORTS HOW TO#
Listing 1 shows how to install the package for subversion. At the time of this writing, the new package management tool pkgng is available, but the older pkg tools will be used to install subversion. This how-to assumes that the system source has not been installed with bsdinstall. Make sure there is at least 6 GB of space available on the hard drive to provide enough space for the system source. The first thing that needs to be completed is an install of FreeBSD 9.2 (amd64) which was just released (See FREEBSD-INSTALL for installation instructions). This article covers the new way to keep up-to-date with the FreeBSD source code. At this point in time, the use of csup/cvsup is no longer supported. With this rebuild, the FreeBSD team moved towards implementing their new process for maintaining source code. The FreeBSD team had to essentially rebuild the binary packages for the FreeBSD 9.1 release because although nothing seemed to have been changed, no backups existed to verify their integrity. The issue was caused by an exposed SSH key from a developer that allowed access to one of the legacy build servers (See FreeBSD Compromise of 2012 for reference). The compromise of the FreeBSD servers led to a complete analysis on how developers and users access the software.
Due to the compromise of two FreeBSD cluster servers, the project moved forward with its intention to replace cvsup and csup. This service had been previously provided by the cvsup and csup programs. FreeBSD users are accustomed to being able to download the entire operating system source code with the ability to compile additional functionality into the kernel and applications.
