 |
|
Hi all,
I am installing a new PC and am pleased to fight for the first time with kernel 3.x and   /usr requirements at boot time via an initramfs .
First battle from dracut : | Code: | | FATAL: Could not load /lib/modules/3.3.8/modules.dep: No such file or directory |
The point is that I have a single DVD player, that my other PC is out of order and back to guarranty. So I used the 2010 live DVD. The point is that under chroot, uname returns the kernel version of the DVD instead of the one from the chroot : 3.3.8 .
I could work around that by setting a simlink to the modules : | Code: | | ln -s /lib/modules/3.3.8-gentoo /lib/modules/2.6.30-gentoo-r5 |
I had also to add : | Code: | | ln -s /lib/modules/3.3.8-gentoo /lib/modules/3.3.8 |
as some process seems to deduce a name instead of peeking the one from the grub configuration.
Then dracut could not install the ext4 module, I had : | Code: | | F: Failed to install ext4 |
I thought that since it is in the kernel, there is no need for it ! Why not, I rebuilt the kernel with the fs drivers as modules : ext2, ext3, ext4. Of course, I rebuilt also external modules with module-rebuild populate & rebuild, which are solely the nvidia drivers, did a depmod -a for the case, and | Code: | | dracut --force '' 3.3.8 |

So I am going to retry with the fs drivers in the kernel, not as modules.
But, ext2_fs.h is here : | Code: | # equery belongs ext2_fs.h

EDIT : same error with fs support compiled in the kernel : missing ext2_fs.h
Any idea please ?
EDIT : sorry, it is a known problem, at least with genkernel. cf
So the solution is to edit /etc/genkernel.conf and to change :

I have also added rootfstype=ext4 into the option of the kernel command in grub.conf :
