All the Cobbler 1.4 default templates are switched to just use
"autopart" now, for complexity reasons. We're still leaving the old disk
partitioning snippets in /var/lib/cobbler/snippets for folks that are
using it.

The very last bit about HTTP_ERROR is spurius, but irrelevant. (What OS
are you running? I think apache.HTTP_ERROR is valid code, which slightly
confuses me).
The text above it though, it correct.
It is saying getVar does not exist, because you need to be using
$getVar(...) instead.
$foo dereferences a variable in Cheetah, or calls a function. In this
case, $getVar(...) is a function.
