pkgng 是 FreeBSD 10.0 開始才有的套件管理機制

有鑑於 FreeBSD 9.1 上的 “pkg_install EOL is scheduled for 2014-09-01” 訊息不斷跳出來提醒 …

終於決定開始著手轉換至新的套件管理機制

方法參照：5.4. Using pkgng for Binary Package Management

FreeBSD 8.4 以後的版本可以直接執行(更早的版本需手動安裝ports-mgmt/pkg):
/usr/sbin/pkg

然後會出現：

The package management tool is not yet installed on your system.
Do you want to fetch and install it now? [y/N]:

當然就回答 y 繼續

接下來就會開始bootstrap…

Bootstrapping pkg please wait
_http._tcp.pkg.FreeBSD.org
Installing pkg-1.2.7_1… done
If you are upgrading from the old package format, first run:

# pkg2ng
Usage: pkg [-v] [-d] [-l] [-N] [-j |-c ] [-C ] [-R ] []

Global options supported:
-d Increment debug level
-j Execute pkg(8) inside a jail(8)
-c Execute pkg(8) inside a chroot(8)
-C Use the specified configuration file
-R Directory to search for individual repository configurations
-l List available commands and exit
-v Display pkg(8) version
-N Test if pkg(8) is activated and avoid auto-activation

接著執行:
pkg2ng 來轉換套件資料庫，花費時間滿明顯跟現有的資料量呈正比 …

中間可能會出現類似這樣的訊息 …

pkg: PACKAGESITE in pkg.conf is deprecated. Please create a repository configuration file

這部分則參照這邊先修掉：pkgng – FreeBSD Wiki

把 /usr/local/etc/pkg.conf 裡面諸如 PACKAGESITE, MIRROR_TYPE, PUBKEY 等 “repository-specific configuration” 拿掉，如果都拿掉會讓這份檔案空掉的話就直接把檔案砍！

建立 repos 資料夾:：mkdir -p /usr/local/etc/pkg/repos

寫設定到 /usr/local/etc/pkg/repos/FreeBSD.conf (以tw為例):

FreeBSD: {
url: "pkg+http://pkg.tw.FreeBSD.org/${ABI}/latest",
mirror_type: "srv",
enabled: yes
}


然後繼續剛剛的 pkg -> pkgng 轉換~

把這一行：
WITH_PKGNG= yes
寫到這裡面： /etc/make.conf

如果之前有寫類似 “NO_WARNING_PKG_INSTALL_EOL=yes” 這類過渡期的設定記得先拿掉…

到這邊差不多就完成了!
