Re: [RFC] SystemTap FAQ

Hi Srinivasa,

Thanks for the FAQ. I have some comments about the FAQ (maybe some comments on how SystemTap handles some of the things in FAQ).


1) Seems like systemtap should be able to handle lack of proper debuginfo
   more clearly. It should be possible to distinguish between non-existent
   debug information and incorrect/inconsistent debuginfo.
   The strip files from the rpms have tags to debug file name.

Let me go through the systemtap error messages in these situations and update the wiki.


2) Why doesn't systemtap attempt to search for
   /usr/modules/`uname -r`/build/vmlinux?

Done


4) Also mention the -k option to save the resulting stap directory.

Already updated.


17) For RHEL5 can use "yum --enablerepo=rhel-debuginfo" to get debuginfo.

Already updated.


18) What happens when someone forgets the "-p4" option?  bz#2725 can
    cause machine to crash. Are there going to be purpose built
    options in systemtap to print out this information?


There is no specific option for listing blacklisted functions. I think
it is good to have this option.

Thanks
Srinivasa DS
