The problem you're encountering is due to a '$' appearing in your
password hashes. With version 2.0.3, snippets are now included via
Cheetah, whereas before, cobbler itself was replacing them with the
appropriate file. The net result is that you need to use #raw & #end
raw tags around your password hashes (ssh keys, etc). Unfortunately,
there is a bug in cobbler whereby, when these snippets fail to parse,
the original 'snippet' line is all that remains in the parsed kickstart,
rather than any sort of error message being included, which is what
happens for parsing errors in the main kickstart file.

I just created a ticket for the issue:
