ubuntu上安装systemtap
因为Ubuntu没有提供kernel debug symbols，systemtap安装后是不能直接在ubuntu上正常使用的。
有人提供了一个安装脚本

为12.04添加apt-get源：
sudo tee /etc/apt/sources.list.d/ddebs.list << EOF
deb http://ddebs.ubuntu.com/ precise main restricted universe multiverse
deb http://ddebs.ubuntu.com/ precise-security main restricted universe multiverse
deb http://ddebs.ubuntu.com/ precise-updates main restricted universe multiverse
deb http://ddebs.ubuntu.com/ precise-proposed main restricted universe multiverse
EOF
为12.10添加apt-get源：
sudo tee /etc/apt/sources.list.d/ddebs.list << EOF
deb http://ddebs.ubuntu.com/ quantal main restricted universe multiverse
deb http://ddebs.ubuntu.com/ quantal-security main restricted universe multiverse
deb http://ddebs.ubuntu.com/ quantal-updates main restricted universe multiverse
deb http://ddebs.ubuntu.com/ quantal-proposed main restricted universe multiverse
EOF
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys ECDCAD72428D7C01
sudo apt-get update
sudo apt-get install -y systemtap
这个快800MB了，有点大
sudo apt-get install linux-image-$(uname -r)-dbgsym
查看systemtap安装是否成功：
stap -l 'module("*").function("*")'
慢且多
或者
sudo stap -e 'probe begin{printf("hello"); exit();}'
