genkernel 3.0.1 How-to

Well, i must agree. A tool that writes INOPERABEL initial ramdisks is far from beeing used by everyone, at my opinion.

I agree it has to be masked, OR this function has to be extra, so that advanced users only can try it.

Does the new version of genkernel copy the .config file created during menuconfig to /usr/share/genkernel/{arch}/kernel-config-2.x or to /etc/kernels/config-{kernelversion} ?

Oh, well... https://bugs.gentoo.org/show_bug.cgi?id=39128

ALRIGHT! Beta 8 of Genkernel 3.0.1 has been released with a MUCH better default config for x86. I ran it with the menuconfig option and checked all of the settings mentioned in this HOWTO and they were all correct OUT OF THE BOX! Ran the compile, install et al and the thing booted first time!

All is forgiven genkernel. Welcome home.

Now I can add cleaning out legacy alsa stuff to my todo list...

Cheers,

Allan

I must say, last night was a hell of a time. Thank the lords for work-provided internet. Here's my journey, which I'm sure some of you have seen in part or in full.

Ran "genkernel --config" and saw the menu. Thinking it looked more or less the same other than the new options for how much do do, did a "genkernel --menuconfig all".
Since I didn't put in the "--install" bit, it didn't install, but I rebooted anyway.
Machine didn't reboot properly. It came up with no networking, despite the 8139too.ko file existing in my modules directory. Seems something must have installed afterall. Looking at the kernel file it hadn't been updated since 10 Jan, so the modules must have been overwritten despite me not putting "--install" in!
Tried to rebuild. No loop, no build. Catch-22 right there. I don't remember the loopback device being needed to build the kernel... or was it always there and the bad config just highlighted it by yanking the loop module from the kernel?
Off to search for documentation. Rebooted in an earlier kernel, 2.6.0-gentoo-r2. This one booted but nvidia.o wasn't present anymore. Tried to "emerge nvidia-kernel" again but that failed "because the /usr/src/linux symlink wasn't present", yet it was, and I did make sure it was pointing at the right version!
Decided to give up on getting XFree86 working and tried building a few more times, using 2.6.0-gentoo-r2 to build 2.6.1-gentoo. No dice, every reboot the same eth0 issue despite the driver being configured in, despite it being present, despite the alias being there! Trying to modprobe it, it said it was already in the kernel, yet eth0 still wouldn't come up!
Gave up and hoped that I could find a fix today. Hopefully that latest 3.0.1 beta works first go (I was on beta6) and the nightmares will be over.

For anyone with the "root block device unspecified or not detected" error, in this thread Corw|n of Amber points out that the initrd from Genkernel doesn't have ReiserFS support.

So, if you (like me) have the error above, the options are:
1) To wait for a new genkerel
2) To create your own initrd

I personally want to create my own initrd, so I'll do some searching and when I find out how to create an initrd, I'll post again.

3.0.1_beta8 indeed rocks. It actually remembers the config from the previous run now... what a relief.

Hi,

I can't seem to get bootsplash to emerge, thus I cannot emerge the latest genkernel-3.0.1-beta9. This is the error message, when I do emerge -U world (trying to emerge bootsplash):

>>> Unpacking bootsplash-0.6-r3.tar.bz2 to /var/tmp/portage/bootsplash-0.6-r3/work

make: *** Waiting for unfinished jobs....

!!! ERROR: media-gfx/bootsplash-0.6-r3 failed.

I'm running gentoo-dev-sources, uname -a:

If someone can help, I'd greatly appreciate it!

Thanks!

Mario

Anybody know of a good 2.6 kernel Guide for manaul configuration? Because after reading this thread I've decided genkernel is a "no go"

I was hoping to find a more sure fire way to get kernel 2.6 up and running. I've always done manual configs in the past and didn't have many problems. But the last few times I did a manual config on 2.6 I was having all sorts of problems (not major, but annoying).

If genkernel creates an initrd with the built in gentoo bootsplash, how do change bootsplash images?

I'll be a little more specific: I've taken the normal steps to change bootsplash themes, and succeeded in getting the theme to change after a certain point in the boot process. However, the original gentoo bootsplash always shows up first, and lasts through the majority of the boot process. I'm assuming that this is because the actual configuration file and graphic is integrated into the initrd file. (I used genkernel)

Now, every set of directions for changing bootsplash images I can find directs users to replace their initrd file. However, I can't do that without getting a kernel panic-- "VFS unable to mount root fs on ram0".

Is there a way around this, or do I pretty much need to rebuild the kernel manually to get the bootsplash I want?

I've been looking into doing this too. If necessary, I'll go back to non-genkernel compiling, but, I've gotten used to genkernel...

Anyways, someone earlier mentioned a RH tool mkinitrd, so I'll give that a try this evening and see how it pans out.
