[Fwd: Re: [et-mgmt-tools] Cobbler, Cheetah and scripts in KS files]

[Aaron Lippold]

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
