I get the "its only good for newbies" line all the time, but I fail to see how. I disable the override-my-kernel-configs and always-do-cleaning-things options and still do make menuconfig or make oldconfig myself ( after doing zcat /proc/config.gz > .config ), but genkernel makes the build-everything, do all the other fun stuff, put it in the right place, update grub fun things for me. Most Relevant lines from my /etc/genkernel.conf #OLDCONFIG="no" MENUCONFIG="no" CLEAN="no" MRPROPER="no" #ARCH_OVERRIDE="x86_64" MOUNTBOOT="yes" # SYMLINK="no" SAVE_CONFIG="yes" USECOLOR="yes" BOOTLOADER="grub" # CLEAR_CACHE_DIR="yes" MAKEOPTS="-j3" # LVM="no" # EVMS="no" # DMRAID="no" BUSYBOX="yes" # MDADM="no" # MULTIPATH="no" # FIRMWARE="no" DISKLABEL="yes" LOGLEVEL=5 then all I do after tuning my kernel every update is genkernel --kernname=MyCurrentMood all It updates grub.conf for me. ( Warning: there are a few glitches that have occured from time to time with the awk-based grub.conf updater, it can be picky, so back it up, once you've gotten it to work once though, it tends to work well every successive time. default=0 timeout=10 splashimage=(hd0,4)/grub/splash.xpm.gz title=Gentoo Linux (2.6.30-gentoo-r4) root (hd0,4) kernel /kernel-CHT-x86_64-2.6.30-gentoo-r4 root=/dev/sda7 vga=868 video=uvesafb:mtrr=3,ywrap,1440x900...@60 softlevel=offline the above should be a good starting template. Note the important "=" in the title segment, and the absense of the "=" in subsequent sections. This is a little known gotcha about grubs configuration, and the awk script is far stricter than grub itself in this case, dying and emitting a blank file if you do it wrong ) Also I managed to tweak my kernel lots so I didn't need an initrd anymore, it was just plain annoying, if you are not so fortunate, use the following pattern ( alternative sets of kernel flags for example only, they all used to be required and I got rid of them recently by selective elimination. Also, the below way to do things will run the genkernel loader which does a lot of magical loading stuff before jumping into init, I did away with that too recently for speed reasons, now genkernel is just a kernel builder for me and doesn't really affect by boot sequence like it does by default ) title=Gentoo Linux root (hd0,4) kernel /kernel-pizzaz-x86_64-2.6.30-gentoo-r1 root=/dev/ram0 init=/linuxrc ramdisk=8192 real_root=/dev/sda7 vga=868 video=uvesafb:mtrr=3,ywrap,1440x900...@60 initrd /initramfs-pizzaz-x86_64-2.6.30-gentoo-r1 ) -- Kent perl -e "print substr( \"edrgmaM SPA nocomil.i...@tfrken\", \$_ * 3, 3 ) for ( 9,8,0,7,1,6,5,4,3,2 );"
