 Posted: Sat Apr 10, 2004 12:14 pm Post subject: migration to kernel-2.6.4 : /linuxrc : 330 : [ : not found |
 |
|
Hi,
I'm searching since 2 days a solution to my problem.
I have a Gentoo (great!) installed and I try to migrate to a kernel 2.6.4. I have updated genkernel and try to do it with this tool.
So I have done a : genkernel all after doing the symbolic link correctly.
I have updated too grub.conf with the
| Code: | kernel (hd1,0)/boot/kernel-2.6.4 root=/dev/ram0 real_root=/dev/hdc3 init=/linuxrc
initrd (hd1,0)/boot/initrd-2.6.4 |
My problem is that I have this message at de begining of boot script part (just after what is logged in dmesg):
| Code: | | /linuxrc : 330 : [ : not found |
and just after
| Code: | ..
umount : /tmp/.initrd : device is busy
* : failed to umount the initrd |
Exept that problem, the system is ok, but I can't umount the initrd manualy... Same message : device is busy...
Some one have an idea over my problem ?
I know that if I don't find a solution I can do the same that in this
topic. But I prefer resolve this one if it's possible.
Here you will find a copy of the initrd, if it can help you...
I don't have any of the two included file from the begining of the script.

I've never used an initrd line in grub.conf, you don't need it (with a 2.6 kernel at least)
Try commenting it out in your grub config and see if it helps.

If I configure grub with just root=/dev/hdc3 and no initrd, it's work.
But what is the avantage of using initrd if it work sin ? And why genkernel use it if it bring more problem than solution ? |

Moved from 'Installing Gentoo' to 'Kernel & Hardware'.

I don't see any advantage in using initrd, I never have.
And I've never used genkernel, and never will.
You should try and learn to compile your own kernels.
