Hi,
Sorry I had to leave the desk for a bit.
Ya it is suposed to be Bash. Which I am sure is the issue but a lot of
my developers are bash folks not python.
I posted the section that seems to be giving python / cheetah fits.
When I escape the ${var} it says end line expected. When cheetah
naturally complains because it does like the var defn.
hmmmm.
thoughts?
Thanks,
Aaron

<aaronlippold> I found that if I just copy the file to the web sever and
reference it with kickstart=http://server/file then it doesn't parse the
ks file. This is a workaround but I would still like to know how to do
this correctly :)

<aaronlippold> google doesn't seem to have an answer for why a X=bla and
then ref X with \${X} would make the cheetah parser is throwing a ,
'Line ending expected', exception.
<aaronlippold> throw an error ... sorry

<mpdehaan> aaronlippold, hi
<mpdehaan> aaronlippold, yes, http:// kickstarts do not parse, there is
a reason for this
<mpdehaan> suppose you want to use a kickstart file straight out of RHN,
for instance, via URL...
<mpdehaan> or if the kickstart is a file another admin maintains
<mpdehaan> so they evaluate only when they are stored on the filesystem
as templates, not whole kickstart files
<mpdehaan> aaronlippold, hmm, perhaps you could post an example to the
Cheetah list
<mpdehaan> ah,
<mpdehaan> so is \${X} supposed to reference a Cheetah var? With
escaping the "X" you won't
<mpdehaan> I mean, the $
<mpdehaan> The reason you escape \$ is to make sure they pass through to
the kickstart file as $
<mpdehaan> Unless that's supposed to be bash code
<mpdehaan> aaronlippold, ping?

Actually, the error is 'Line ending expected'
