# 安装「实例共享工具」到 /usr/local/dsh-runtime/bin（+ /usr/local/bin 软链）
|
||
#
|
||
# 为什么共享而不是每个用户装一份（档案 46）：
|
||
# · 实例内 `/usr` 是 ro-bind，且 `/usr/local/bin` 在实例 PATH **首位** →
|
||
# **宿主装一次，全部实例（含新用户）立即可见，零代码、无需重启**；
|
||
# · 用户侧装不上（`/usr` 只读 + 无 sudo），且每人一份会重复占磁盘、版本还不一致。
|
||
#
|
||
# 迁移：整个 `/usr/local/dsh-runtime/` 就是一个打包单元 →
|
||
# tar czf dsh-runtime.tar.gz -C /usr/local dsh-runtime
|
||
# 目标机解压回原位后跑本脚本（已存在则只重建软链）。
