Network Protocols
The ip6fw(8) packet filter has been removed. Since ipfw(4) has gained IPv6 support, it should be used instead. Please note that some rules might need to be adjusted.
由於ipfw加入IPv6支援 , 所以 ip6fw已經被移除.
The KAME IPsec implementation has been removed. In its place, FAST_IPSEC is now the only IPsec implementation supported by the FreeBSD kernel. The IPSEC kernel configuration option, which formerly enabled KAME IPsec, now enables FAST_IPSEC. FAST_IPSEC now supports both IPv4 and IPv6, uses fine-grained kernel locking, and supports hardware cryptographic acceleration.
FAST_IPSEC (hardware-accelerated IP Security Protocols)是唯一FreeBSD kernel之支援實做的 IPsec 協定.
The default minimum number of nfsiod kernel threads ( sysctl(8) variable vfs.nfs.iodmin) has been changed from 4 to 0.
nfsiod (local NFS asynchronous I/O server)預設的啟動數量由4改為0
File Systems
[amd64, i386] Experimental support for the TMPFS file system has been added. TMPFS is an efficient memory file system originally developed for the NetBSD project during the Google Summer of Code. More information can be found in the tmpfs(5) manual page.
從NetBSD發展的TMPFS 以實驗性質方式加入檔案系統.
The fdisk(8) program now supports a -p flag to print the slice table in fdisk configuration format
fdisk指令新增 -p 參數 用來顯示 slice table
The freebsd-update(8) command now supports an upgrade command to perform binary upgrades between different versions of FreeBSD.
freebsd-update指令新增 upgrade 指令 用來執行進行不同版本間的 binary upgrade
/etc/rc.d Scripts
The ftpd script for stand-alone ftpd(8) has been added
新增 ftpd script 用來支援 stand-alone 型態的ftp daemon
The sendmail script no longer rebuilds the aliases database if it is missing or older than the aliases file. [MERGED] If desired, set the new rc.conf option sendmail_rebuild_aliases to "YES" to restore that functionality.
sendmail 這個script , 將不再建立 aliases 資料庫, 若仍有此需要 則在 rc.conf 加入
sendmail_rebuild_aliases="YES"
The /etc/rc.d/nfslocking script has been deprecated and will be removed in a future release. It has been replaced by the /etc/rc.d/lockd and /etc/rc.d/statd scripts
nfslocking script將會在不久之後被移除, 由 lockd 和 statd 這兩個script取代
Release Engineering and Integration
The default partition sizing algorithm of the sysinstall(8) utility has been changed
sysinstall 預設安裝的partition 大小改變, 依照硬碟容量不同而稍有異動.
Upgrading from previous releases of FreeBSD
[i386, amd64] Beginning with FreeBSD 6.2-RELEASE, binary upgrades between RELEASE versions (and snapshots of the various security branches) are supported using the freebsd-update(8) utility. The binary upgrade procedure will update unmodified userland utilities, as well as unmodified GENERIC or SMP kernels distributed as a part of an official FreeBSD release. The freebsd-update(8) utility requires that the host being upgraded have Internet connectivity.
自 6.2RELEASE後, 可以透過 freebsd-update 程式進行版本更新, binary upgrade程序將會更新未經修改的使用者領域的程式, 此 freebsd-update升級程序,需要擁有internet 連線能力,
An older form of binary upgrade is supported through the Upgrade option from the main sysinstall(8) menu on CDROM distribution media. This type of binary upgrade may be useful on non-i386, non-amd64 machines or on systems with no Internet connectivity.
另外一個較老的binary upgrade方式是透過 sysinstall 透過Upgrade參數選項,經由光碟更新.
此總方式較適用 非i386 amd64 的機器使用,升級時不需要internet連線能力.
Source-based upgrades (those based on recompiling the FreeBSD base system from source code) from previous versions are supported, according to the instructions in /usr/src/UPDATING.
Source-based 的upgrade方式仍然可以使用,請依照 /usr/src/UPDATING 指示操作
Important: Upgrading FreeBSD should, of course, only be attempted after backing up all data and configuration files.
不管用任何方式升級FreeBSD ,請務必備份所有資料及設定檔.
