如何不透過VirtualBox執行

---

參考資料：
1. Application_SDK
2. Howto-build-for-Sailfish-OS
3. running-sailfishos-build-engine-outside-virtualbox-vm

步驟如下：
1. 開啟VirtualBox(Sailfish OS Build Engine)
2. 登入ssh並且建立一個新使用者(擁有root權限)
3. 確定權限(xxx是建立的使用者名稱)

$ ssh -p 2222 -i /home/xxx/SailfishOS/vmshare/ssh/private_keys/engine/root root@localhost

4. 複製系統到本地端

$ cd
$ su
# mkdir /opt/sailfishos-buildengine
# rsync --numeric-ids -xazuv -e "ssh -p 2222 -i /home/xxx/SailfishOS/vmshare/ssh/private_keys/engine/root" root@localhost:/ /opt/sailfishos-buildengine 

5. 建立chroot腳本(/opt/run-sailfishos-buildengine.sh)

#!/bin/bash
USER=xxx
USERDIR=/home/$USER
SDK=/opt/SailfishOS
BUILDENGINE=/opt/sailfishos-buildengine

if [ $EUID -ne 0 ]; then
  echo "This script must be run as root." 1>&2
  exit 1
fi

if cmp -s /proc/$PPID/mountinfo /proc/self/mountinfo; then
  exec unshare -m -- "$0" "$@"
  echo "$0 must be run in private namespace."
  exit 1
fi
