Hi folks -
Next problem. Using current Fedora kernel. Custom initrd has the ext3 and
jbd modules, installs them, and is able to mount an ext3 partition, all
inside the initrd. That's great.
At the end of the initrd script, Linux wants to mount the root filesystem
again, okay, BUT the Redhat kernel does not have ext3 compiled in, its as a
module. This shouldn't matter because the initrd has loaded the jbd and ext3
modules. Yet despite this the kernel is unable to mount the same ext3
filesystem that the initrd was, apparently because ext3 was not compiled in
and is 'not on its list'. It instead mounts it as ext2 and then blows up
later in /etc/rc.sysinit when that tries fsck on it. The kernel commandline
rootfs=ext3 has no effect.
Any clues as to how Redhat manage to mount ext3 root filesystems or what is
wrong with my picture?
