opkg-svn 的PKGBUILD和通过opkg在线安装制作rootfs的方法

从AUR上 下载, yaourt -G opkg-svn

修改 ./configure --prefix=/usr --with-opkglibdir=/var/lib 和版本号变为650

# opkg-query-helper.py 位于 openembedded-core/scripts目录下

不指定 --conf (或 -f) 则默认查找 ${D}/etc/opkg/目录下的配置

export D=${ROOTFS_DIR} 非常重要，因为pkg_postinstall文件会判断 $D 来确定是否为在交叉方式安装包

OFFLINE_ROOT 变量在opkg源代码里会操作使用, OPKG_OFFLINE_ROOT变量则由 /usr/bin/update-alternatives 判断是否为外部rootfs操作

--offline-root <dir> offline installation of packages. 使用--offline-root离线安装模式

cat angstrom_rootfs/etc/opkg/angstrom-base.conf

src/gz angstrom-base http://us.feeds.angstrom-distribution.org/feeds/unstable/ipk/glibc/armv7a/base

mkdir rootfs/etc/opkg -pv

mkdir rootfs/var/lib/opkg -pv

注意要将arch.conf拷到rootfs/etc/opkg 目录下
