As others said, it did indeed prove to be the case that current versions of glibc do require a Linux 2.6 kernel to be running in order to complete the installation.

I proceeded to download, configure and install a 2.6 kernel, running on my current host system, using either the gcc compiler that I had already downloaded to the lfs userid or the one that was already installed upon the host.

As predicted, it turned out to be important to build a "module free" kernel. That is, one in which all of the necessary functionality was built into the kernel and always-resident. And by the way, you'll be rather startled at how much faster this kernel runs than the one you've been using.

I made extensive use of a series of articles at http://www.LinuxDevices.com/articles/AT3855888078.html for pointers on how to support booting of the "old" (host) kernel or the "new" (2.6) kernel on the same system.

From then on, you can proceed with the LFS instructions pretty much exactly-as-stated.

Contrary to what the book said. I built modules in the kernel. Then Installed hotplug-2004_09_23 the installed the blfs-bootscripts-6.0 for hotpluging.

Although, It does go kinda slow, and I will probably recompile the kernel with less modules, I think for some cases I will need coldpluging. Like for when I plug-in a usb device or removable drive. (I don't actually know)

I dunno. When you can rather quickly compile a kernel that has exactly whatever you need, and do so in the space of about ten minutes flat, then it turns out to be rather nice to include exactly whatever you need and nothing more. If you go out and need a hotplug device, you can whip up a new kernel very fast.
