Thanks, I didn't know about this -- However, for my particular
example of a broken snippet, it doesn't help. It just stops working
with a non-helpful error message when it gets to the kickstart with
the problem:<br>
<br>
<blockquote>Exception occured: <type 'exceptions.NameError'><br>
[etc]<br>

Thanks again! This will probably help for some things. Still, it
doesn't appear to help with my example broken snippet. At least,
not when I did this:<br>
#errorCatcher Echo<br>
#if $break_me == 1<br>
# no #end if...<br>
<br>
I did notice that if you have an undefined variable, it changes the
behavior completely. Without errorCatcher, the kickstart would just
have:<br>
$SNIPPET('snippet_with_error')<br>
but with errorCatcher, the kickstart is printed with the undefined
variable in it. Maybe this isn't a good thing, because there's no
error message anywhere I can find. i.e. all the errorCatcher does
in this case is make the error silent! At least when "$SNIPPET" is
present I know there's an error in it :)</div></blockquote><div><br></div><div>Cobbler injects the error catching class silently before parsing, so that's why that won't work. You could modify templar.py if you wanted, here's the patch that I added for 2.4.0:</div>
