Bug#522928: partman/early_command not supported in Lenny

["Kevin Schwartz" <kevin.schwartz@tni-systems.net>]

After reading through this link I thought that the partman/early_command was
supported in Lenny:

http://d-i.alioth.debian.org/manual/example-preseed.txt

But this is not the link the to the official Lenny preseeding example. That
link is here:

http://www.debian.org/releases/lenny/example-preseed.txt

The official example-preseed.txt file clearly does not have a reference to
partman/early_command. So I guess that this command is not supported under
Lenny.

Thanks,
Kevin
