is your root partition ext3? have you changed /etc/fstab so it reads /dev/hda1 (eg) instead of /dev/BOOT? are you absolutly positive ext3 support is compiled in the kernel and not as a module?
(if you havent, fyi /dev/ROOT mounts properly because you specified root=/dev/hda3 (eg) on the kernel command line)

Did you mount /boot before copying the new kernel? You did try and copy the new kernel to /boot, correct?

there's my fstab:

TheCoop · Posted: Sat Oct 19, 2002 9:22 pm Post subject:

at the end of your /boot line, change 0 0 to 1 2
at the end of your / line, change 0 0 to 0 1

if you want to, you could also put a line for the floppy drive:
/dev/fd0 /mnt/floppy auto noauto,users 0 0

i think maybe i've installed the ext3 wrong, how do i install it right, so i will know if i did it well, (i read the manual but i didn't see anything like that)

In the kernel config (make menuconfig):

File Systems ->
Kernel automounter v4 support
Ext3 journalling filesystem support (all compiled in)

if you have already got that, add ext3 debugging support as well

i got it, on the stupid manual i listen to him was write
do make menuconfig && make dep && bzImage
and they forgot to remain that i need to do cp /usr/src/linux/arch/i386/somethingiforgot/bzImage /boot

basically, to recompile the kernel:

I have a similar problem with devfs support. I have recompiled my kernel a number of times now with gentoo sources and vanilla both including devfs support. However, on bootup, I get the "DEVFS support needs to be compiled in kernel" warning.

My boot and root partition are ext3.

Because you can't mount /boot, the bzImage gets copied off into the wild blue yonder, and basically vanishes.

You'll need to get working ext3 support into the kernel before you can mount the boot partition.

Offhand, I'd say boot from the liveCD, chroot into your gentoo install, and built the kernel there.

Isn't ext3 just ext2 with a journal file? For tasks like copying files to it, I would expect that you should be able to mount it as ext2, i.e. pass the -t ext2 parameter explicitly to mount.

@MacMasta: apologies if you were just being metaphoric, but if you copy something to /boot when /boot is not mounted, it goes to the /boot directory on the root partition. It doesn't vanish. Unmount /boot and ls and it'll still be there, taking up space on the root filesystem.

OK, I have the ext3 file support now and things look a lot better

. What I did was boot off the live CD, re-emerged gentoo kernel (probably not necessary), set up the .config, compilied, and copied the bzImage to the /boot directory.

Upon reboot - happy system!

I think everytime I recompiled and copied the new image, it was going to the root partition as Rac said. MacMasta's solution did the trick!

Thanks everybody for the help!!! :lol:

I do have an error in my fstab that shows up now on botup... Something about an error in line 17 and invalid mount points. I was way too tired at the time to do any further investigation, so I'll deal with that tonight.

Thanks again, it's nice knowing there's helpful peeps out there to help out the newbie ranks.

FYI... On a side note, I did forget to enable devfs on my first compile.

I'm so stoked...

found that after inserting a couple of tabs in the appropriate places in fstab I now boot completely clean!!

In the scheme of life this may seem insignificant to some, but I feel like I just climbed Everest or something!
