Mainstream distributions use initrd as they support vast number of different configurations, thus they build most of the drivers as modules. In LFS, we don't use initrd/initramfs as the system is targeted to the machine you are building to, or in other words, only one configuration. Thus, it's required to properly configure the kernel for only one machine, which means everything (or at least the required parts) is built as built-in instead of module. Without initrd/initramfs, you need to at least have drivers for Disk controller and the file system your LFS partition resides at. You can consult my basic kernel doc that gets past the kernel panic that says something like "not syncing VFS ... unable to mount root fs at block ..." http://www.linuxfromscratch.org/~krejzi/basic-kernel.txt Note that the doc is a bit old and some options might have a bit different na mes. -- Note: My last name is not Krejzi.
