explanation of where to see exactly how it's created.

The 2.6 kernel build process always creates a gzipped cpio format initramfs
archive and links it into the resulting kernel binary. By default, this
-archive is empty (consuming 134 bytes on x86).
-
-The config option CONFIG_INITRAMFS_SOURCE (in General Setup in menuconfig,
-and living in usr/Kconfig) can be used to specify a source for the
-initramfs archive, which will automatically be incorporated into the
-resulting binary. This option can point to an existing gzipped cpio
-archive, a directory containing files to be archived, or a text file
-specification such as the following example:
+archive contains nothing but the two objects:
+
+ /root
+ /dev/console
+
+You can verify this by examining the default_initramfs() routine in the
+file scripts/gen_initramfs_list.sh:
+
+default_initramfs() {
+ cat <<-EOF >> ${output}
+ # This is a very simple, default initramfs
+
+ dir /dev 0755 0 0
+ nod /dev/console 0600 0 0 c 5 1
+ dir /root 0700 0 0
+ # file /kinit usr/kinit/kinit 0755 0 0
+ # slink /init kinit 0755 0 0
+ EOF
+}
+
+Alternatively, the config option CONFIG_INITRAMFS_SOURCE (in General
+Setup in menuconfig, and living in usr/Kconfig) can be used to specify
+different contents for the initramfs archive. This option can point to an
+existing gzipped cpio archive, a directory containing files to be archived,
+or a text file specification such as the following example:
dir /dev 755 0 0
nod /dev/console 644 0 0 c 5 1
