The terminilogy of initramfs/initrd is used pretty lossely, even by |
| 2 |
kernel devs. My understanding is that typically 'initrd' is refering to |
| 3 |
an actual filesystem image (created on a loopback) and get's mounted a a |
| 4 |
ramdisk and used at the root filesystem. Where as an initramfs image is |
| 5 |
just a CPIO archive that gets unpacked into a tmpfs filesystem that is |
| 6 |
then mounted as root. initramfs images can be either built into the |
| 7 |
kernel image or loaded from an external file. Byeond the format there's |
| 8 |
not much difference bewteen them. In theory an initramfs iamge could be a |
| 9 |
bit smaller as it doesn't have to drag around the filesystem metadata |
| 10 |
with it. Also, as it's just a CPIO archive a driver for the |
| 11 |
filesystem type need not be built into the kernel. |

Wikipedia considers initramfs & initrd to refer to the same thing: |
