Display only one kernel entry in grub-pc (lucid)

[Nicolas Michel]

Hello,

For a end-user, I want to setup grub-pc on Ubuntu Lucid to display only 
one kernel entry. So if an update install a new kernel version it will 
be transparent for him.
With grub-legacy there was the "howmany" option.
With grub-pc I found a french article (on ubuntu.fr) which talk about 
modifying the variable NBLISTMAX in the grub script 10_linux. But that 
tip was probably written for Karmic because the same script in Lucid 
don't seem to use that variable anymore.

-> I found nothing in english about this need.

Someone know how to do it?

Thank you,
nm

ps : I want for that user to have only the choice between Linux and 
Windows. (I successfully found how to disable memtest et recovery entries)
