Building a custom kernel


I've been trying to build my own custom kernel on my red hat 8.0 system. I've followed the directions verbatim using the "The Official Red Hat Linux Customization Guide", but I can't boot up the custom kernel. I get the following error:

"net4: Unix Domains sockets 1.0/SMP for linux Net4.0........ds: no socket drivers loaded.......VFS: Cannot open root device "LABEL=/" or 00:00 ...............Please append a correct "root=" boot option .....Kernel Panic VFS: unable to mount root fs."

Does it have something to do with my file system. Can anyone helP? I did it once before and didn't encounter any problems. Thanks

You'll have to spit out your lilo.conf file. It may be that there's nothing wrong with your kernel your just booting it incorrectly.

I use grub instead of lilo. Here it is:

default=3
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Linux (2.4.18-14custom)
root (hd0,0)
kernel /vmlinuz-2.4.18-14custom ro root=LABEL=/ hdc=ide-scsi
initrd /initrd-2.4.18-14custom.img
title Red Hat Linux (2.4.18-14.custom.070203)
root (hd0,0)
kernel /vmlinuz-2.4.18-14.custom.070203 ro root=LABEL=/ hdc=ide-scsi
initrd /initrd-2.4.18-14.custom.070203.img
title Red Hat Linux (2.4.18-14.custom.070103)
root (hd0,0)
kernel /vmlinuz-2.4.18-14.custom.070103 ro root=LABEL=/ hdc=ide-scsi
initrd /initrd-2.4.18-14.custom.070103.img
title Red Hat Linux (2.4.18-14)
root (hd0,0)
kernel /vmlinuz-2.4.18-14 ro root=LABEL=/ hdc=ide-scsi
initrd /initrd-2.4.18-14.img

Here's how I create the custom kernel too.


cd /usr/src/linux-2.4
make mrproper
make xconfig change to pentium 4 change CONFIG_SOUND_OSS =M
make dep
make clean
change version on Makefile
make bzImage
make modules
make modules_install
make install.


Maybe that would help too.

lilo

Have you tried getting rid of the LABEL portion thats added by redhat. Just do it like this

root = /dev/hdxx

where xx is the dev with your / partition (example /dev/hda1)

I have no idea why redhat tries to use LABEL but it's not necessary and is known to cause some people issues.

Or better yet use grub.
grub == no more running /sbin/lilo

good luck to you
