only partially true. as i understand it (and i asked about this way
back in history once upon a time), you only need an initrd if you want
to mount the *root* filesystem by label.
the explanation i got back then was that initially mounting the root
filesystem is done by the kernel in kernel space, where there is no
knowledge of labels -- you have to use device names. once that's
done, the remaining mounts out of /etc/fstab are done in user space,
and labels are fine.
if you use an initrd, then the mounting of the root filesystem will
(somehow) be able to use labels -- perhaps the initrd forces the
mounting to happen in user space?
can someone clarify this?
