【Linux】chroot與移植


標籤： ,

最近有同事把我們build code的環境由redhat移植到ubuntu。老實說以前我都覺得要重作corss-compiler才能重建build code環境。沒想到直接用ubuntu開機，mount全部的東西，tar起來後。用chroot也能達到類似的功能。

  1. boot into ubuntu
  2. mount vm partitions from vm
  3. tar all files/folder under root(/) directory
  4. umount vm partition from vm
  5. untar
  6. chroot /folder-name
