adding a kernel from backports

[Rob Owens <rowens@ptd.net>]

In order to get a wireless card working, I need to install a kernel from
lenny backports.  I get this message:

You are attempting to install an initrd kernel image (version          ↑ 
2.6.30-bpo.2-486). This will not work unless the boot loader is
configured to use an initrd.
An initrd image is a kernel image that expects to use an INITial
Ram Disk to mount a minimal root file system into RAM and use that for
booting.
The boot loader must be configured to use such images and the
system   ▒ 
will not boot until this is done.
▒ 
This message will appear for any new kernel installation unless the
following is added to /etc/kernel-img.conf:      

"do_initrd = Yes"    


Is there any reason not to do this on a live system?  I ask because my
/etc/kernel-img.conf file is empty on my live system, while my Lenny
system installed on a hard disk has this in /etc/kernel-img.conf:

do_symlinks = yes
relative_links = yes
do_bootloader = no
do_bootfloppy = no
do_initrd = yes
link_in_boot = no
postinst_hook = update-grub
postrm_hook   = update-grub

By the way, I'm using syslinux as my bootloader.
