Hi all:
I'm trying to rebuild the anaconda installer for Centos 4.0 (i386) to add some RPMs and do some other things, and I've run into a problem. I've done lots of anaconda rebuilds for Tao Linux 1.0, and I'm bringing those bits forward into Centos 4.0. The all-knowing web hasn't turned up anything useful. It looks like the PXE-loaded kernel unpacked and mounted the initrd OK, but then things went awry (quickly). Anyone seen this on a PXE boot of an anaconda build?
<snip> RAMDISK: Compressed image found at block 0 VFS: Mounted root (ext2 filesystem). VFS: Cannot open root device "<NULL>" or unknown-block(3,2) Please append a correct "root=" boot option Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,2)
Help or pointers to applicable docs very welcome.

I get that when my initrd is messed up. I'll generally re-create it and things will be resolved. Also, you may try bumping up the ramdisk size in your pxelinux.cfg
append ramdisk_size=20000
I create my initrd's with:
zcat /tmp/initrd.img > /tmp/initrd.fs mkdir /mnt/initrd mount -o loop /tmp/initrd.fs /mnt/initrd
make any changes...like putting in the new init and loader from anaconda-runtime
umount /mnt/initrd cat /tmp/initrd.fs | gzip -9 > /tmp/initrd-new.img
