[gentoo-user] Getting genkernel to use newer dmraid

[gentoo-user] Getting genkernel to use newer dmraid

[Daniel Frey]

Hi all,

I've been trying to get genkernel to use a newer version of dmraid.
For some reason, genkernel is using a build from 2006 (!)

I've tried an ubuntu livecd which uses a build that's available in
portage that works with my fakeraid. All this to try to dual-boot
using a raid 1+0.

I've discovered /etc/genkernel.conf has settings for this, so I tried
changing them:
-----
#DMRAID_VER="1.0.0.rc14"
DMRAID_VER="1.0.0.rc16"
DMRAID_DIR="dmraid/${DMRAID_VER}"
#DMRAID_SRCTAR="${DISTDIR}/dmraid-${DMRAID_VER}.tar.bz2"
DMRAID_SRCTAR="/usr/share/dmraid/dmraid-1.0.0.rc16-3-prepatched.tar.bz2"
DMRAID_BINCACHE="%%CACHE%%/dmraid-${DMRAID_VER}-%%ARCH%%.tar.bz2"
-----

After that I issued a `genkernel --lvm --dmraid initramfs` and got this:
-----
ubuntu / # genkernel initramfs

I can see that the dmraid directory is invalid, but I do not know how
to correct this?

I've not tried making an initramfs myself (I do not know how) but have
been building my own kernels since 2004. I couldn't really find
anything on genkernel after googling other than the basic usage.

Can anyone help?

You sure about this one?

That lack of a leading "/" looks mighty suspicious

The only two lines I changed are the ones I commented out (so I only
changed DMRAID_VER and DMRAID_SRCTAR.) If I revert the changes, the
default initramfs with the included dmraid build properly.

I suspect there's a build directory somewhere buried deep down that I
can't find. I'm going to try to dig into this a little deeper...
although I do need a new motherboard soon. I'm starting to dislike the
reliability of Asus motherboards. I've had three fail now (different
models) so I ordered an Intel board to replace this current one. I
wouldn't be surprised at this point if the motherboard is the cause of
my grief.

Thankfully I have a laptop or I'd be going through serious internet
withdrawal symptoms. :)
