extlinux-update: command not found anymore

[T o n g <mlist4suntong@yahoo.com>]

Hi, 

Having installed extlinux in sid, I still don't have the /boot/extlinux/
linux.cfg file, so I tried to run extlinux-update to generate one. 
However, I got: 

    extlinux-update: command not found

Also, https://packages.debian.org/search?
searchon=contents&keywords=extlinux-
update&mode=exactfilename&suite=unstable&arch=any says, 

 You have searched for files named extlinux-update in suite sid, all 
sections, and all architectures.
 Sorry, your search gave no results

So there is a new way that I should install and use extlinux? Thanks
