FreeBSD 9.2-RC4 發布
FreeBSD是類UNIX操作系統，它基于加州伯克利大學的“4.4BSD-Lite”發行并帶有一些“4.4BSD-Lite2”增強，面向i386、amd64、IA-64、arm、MIPS、powerpc、ppc64、PC-98、UltraSPARC等平臺。它還間接地基于“386BSD”，此乃William Jolitz對加州伯克利大學的“Net/2”往i386系統上的移植，盡管如今只有極少的代碼保留下來。FreeBSD被全世界的公司、因特網服務提供商、科研人員、計算機專家、學生、家庭用戶等用于他們的工作、教育、娛樂中。FreeBSD帶有20000多個軟件包，它們是預編譯和打包好了、便于安裝的軟件，并覆蓋了廣闊的應用領域：服務器軟件、數據庫和網頁服務器、桌面軟件、游戲、網絡瀏覽器和商務軟件，而這一切都是免費和易于安裝的。
Development work on FreeBSD 9.2-RELEASE continues with the latest release candidate as announced by Glen Barber earlier today:
" The fourth release candidate builds of the 9.2-RELEASE release cycle are now available on the FTP servers for the amd64, i386, ia64, powerpc, powerpc64, and sparc64 architectures. This is expected to be the final release candidate for the 9.2-RELEASE cycle. Changes between -RC3 and -RC4 include: revert the tribute boot loader logo as the default logo; fix a file system bug that would cause removed files to fail to dereference vnodes until the file system was forcibly unmounted and remounted; fix a rtadvd(8) segmentation fault on service reload; create and correct ownership and permissions of /var/authpf in the standard mtree; fix a NFS deadlock; stop SIOCSIFADDR, SIOCSIFBRDADDR, SIOCSIFDSTADDR and SIOCSIFNETMASK at the socket layer rather than pass them on to the link layer without validation or credential checks....</span>"
