Literally, just the questions as of now :-)
Please add any questions we've missed; more importantly, please attempt
to answer a few of them too.
Once answered, this will live in the SystemTap wiki.
1) I have installed SystemTap but am getting a "semantic error: libdwfl
failure (missing kernel debuginfo): No such file or directory", when I
try to run a script. What am I missing? How do I fix it?
2) What config options need to be enabled to be able to use SystemTap on
custom built kernels?
3) I have a kernel built with options listed in (2), but still can't get
SystemTap to work. What am I missing?
4) Is it possible for me to view the kernel module generated by SystemTap?
5) How do I run prebuilt SystemTap modules?
6) What should I do when some tapsets functions fails to resolve like
"semantic error: unresolved arity-1 function: identifier 'log'"
7) This is way cool! I want to write my own scripts. Where do I look for
more information?
8)Is it possible to override some of the macros in SystemTap generated "C"
module.
9) What are tapsets?
10) I see that there is no tapset for my favourite subsystem. What do I
do?
11) I hear the latest Linux Kernels come with marker support. Does
SystemTap support markers?
12) I am a non-root user, but still want to run SystemTap scripts. Is
that possible?
13) This is fantastic! But how does it all work?
14) Do I have to be a RedHat Enterprise Linux/Fedora user to be able to
use SystemTap?
15) I found a bug when using the tool. How do I report it?
16) I'd like to contribute to the project. Where to I start?

Srinivasa
