I updated to the latest kernel with entropy, but I had to manually edit the /boot/grub/menu.lst to put the latest kernel at the top of the list. Moreover, removing old kernels does not remove the entries from the /boot/grub/menu.lst file. I believe it would be beneficial to have entropy edit the /boot/grub/menu.lst file and do these edits when updating the kernel.
Out of curiosity, I recompiled the kernel with portage to see what would happen, but portage doesn't do what I want it to do either.
Thanks for your time.
