Description Petr Muller 2008-04-08 16:09:45 UTC

Description of problem:
I haven't been succesful when running a command under ftrace. If I attach to 
some already running pid, everything seems to be ok. But if I run direct 
command, then nothing happens and the program seems to never end. I wasn't able 
to run any of the examples from the man page.

Version-Release number of selected component (if applicable):
frysk-0.0.1.2008.03.19.rh1-1.el5

How reproducible:
seems like always

Steps to Reproduce:
1. ftrace -sys= ls (but any options can be used, none works)
2. see execvp: No such file or directory error message
  
Actual results:
no workie workie

Expected results:
ls output is shown, along with the captured syscalls

Additional info:
# ftrace -sys= -- ls
execvp: No such file or directory

Comment 1 Mark Wielaard 2008-04-08 16:14:53 UTC

This is similar to this fedora bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=440323

Workaround for now, use full absolute paths to the binary you want to frace: 
ftrace -sys= /bin/ls
