~/.systemtap/cache
Data directory for cached SystemTap files.
/tmp/stap*
Temporary directory for SystemTap files, including translated C code and kernel

5.2 Installation and Setup
As SystemTap needs information about the kernel, some kernel-related packages
must be installed in addition to the SystemTap packages. For each kernel you want to
probe with SystemTap, you need to install a set of the following packages that exactly
matches the kernel version and flavor (indicated by * in the overview below).
IMPORTANT: Repository for Packages with Debugging Information
If you subscribed your system for online updates, you can find “debuginfo”
packages in the *-Debuginfo-Updates online installation repository rel-
evant for SUSE Linux Enterprise Server 11 SP3. Use YaST to enable the
repository.
For the classic SystemTap setup, install the following packages (using either YaST or
zypper).
• systemtap
• systemtap-server
• systemtap-docs (optional)
• kernel-*-base
• kernel-*-debuginfo
