<undefined>* **安裝所需要的工具**</undefined>

$ sudo apt-get install pbuilder cowbuilder ubuntu-dev-tools

pbuilder - personal package builder for Debian packages

cowbuilder - pbuilder running on cowdancer

cowdancer - Copy-on-write directory tree utility.

ubuntu-dev-tools: /usr/bin/pbuilder-dist

ubuntu-dev-tools: /usr/bin/cowbuilder-dist

<undefined>* **以 Debian unstable 為例**</undefined>

在 ~/bin/ 底下建立 Soft link pbuilder-unstable-amd64 -> /usr/bin/pbuilder-dist

$ pbuilder-unstable-amd64 create # 建立基本環境

$ pbuilder-unstable-amd64 update # 更新環境

$ pbuilder-unstable-amd64 build hello_2.10-0.1.dsc # 編譯該套件

pbuilder 1st: 1m38.364s, 2nd: 1m50.065s, 3rd: 1m24.354s

cowbuilder 1st: 1m32.800s, 2nd: 1m42.222s, 3rd: 1m7.449s

**sbuild**

[](https://wiki.debian.org/sbuild)https://wiki.debian.org/sbuild

<undefined>* **安裝所需要的工具**</undefined>

$ sudo apt-get install sbuild ubuntu-dev-tools

<undefined>* **以 Debian unstable 為例**</undefined>

$ mk-sbuild --arch amd64 --distro debian unstable # 第一次執行時會把你加入 sbuild 群組

$ newgrp sbuild # 馬上得到 sbuild

$ mk-sbuild --arch amd64 --distro debian unstable

 To CHANGE the golden image: sudo schroot -c source:sid-amd64 -u root

 To ENTER an image snapshot: schroot -c sid-amd64

 To BUILD within a snapshot: sbuild -A -d sid-amd64 PACKAGE*.dsc

$ sbuild -A -d sid-amd64 hello_2.10-0.1.dsc

 E: Local archive GPG signing key not found

 I: Please generate a key with ’sbuild-update --keygen’

$ sbuild-update --keygen # 第一次需要產生一組公私鑰給它用

$ sbuild -A -d sid-amd64 hello_2.10-0.1.dsc

sbuild, 1st: 0m59.525s, 2nd: 0m59.437s

**pdebuild**

pdebuild - pbuilder way of doing debuild

這個就比較沒有那麼彈性，只能依照 ~/.pbuilderrc 裡面設定或是指令所下的參數來建立環境

$ sudo apt-get install debian-archive-keyring

$ sudo pbuilder --create --mirror [](http://free.nchc.org.tw/debian)http://free.nchc.org.tw/debian --distribution unstable --architecture amd64 --debootstrapopts --keyring=/usr/share/keyrings/debian-archive-keyring.gpg # 產生 Debian unstable amd64 的環境

$ cd ~/workshop/hello-2.10 # 直接進到 Debian source package 解開後的目錄底下

$ pdebuild

<undefined>* **Host 為 Debian **</undefined>

$ sudo pbuilder --create --mirror [](http://free.nchc.org.tw/debian)http://[free.nchc.org.tw](http://free.nchc.org.tw/debian)/debian --distribution unstable --architecture amd64

如果沒有特別設定的話，Debian binary package 會產生在 /var/cache/pbuilder/result 底下

* "Only the [root user](http://en.wikipedia.org/wiki/Superuser) can perform a chroot. This is intended to prevent users from putting a [setuid](http://en.wikipedia.org/wiki/Setuid) program inside a specially crafted chroot jail (for example, with a fake [/etc/passwd](http://en.wikipedia.org/wiki//etc/passwd) and [/etc/shadow](http://en.wikipedia.org/wiki//etc/shadow) file) that would fool it into a [privilege escalation](http://en.wikipedia.org/wiki/Privilege_escalation)."  -- [Wikipedia](http://en.wikipedia.org/wiki/Chroot)

* "Schroot allows users to execute commands or interactive shells in different <u>[chroots](https://wiki.debian.org/chroot)</u> (see <u>[schroot](https://packages.debian.org/schroot)</u>)." -- [Debian wiki](https://wiki.debian.org/Schroot)
