   This isn't entirely true.  I'd say something like, "The file system and 
drive interface for your root partition SHOULD NOT be compiled as modules."

   Red Hat (and many other vendors) ship a kernel with very little 
compiled statically, and almost every option built as a module.  The 
installer builds an Initial RamDisk (initrd) with the modules for SCSI 
controllers, RAID, and non-ext2 filesystems, if you need them.

   In your case you'd need a command like:
# /sbin/mkinitrd --with=jbd --with=ext3 /boot/initrd-[kernel-version] \ 
 [kernel-version]

  You'd also have to have a line in your bootloader config file such as:
        initrd /boot/initrd-[kernel-version]

   All of this is unnecessary if you compile the options into your kernel, 
which is really the right way to do things.

It's lonely at the bottom too, just more crowded.
