No, a cp command is almost guaranteed to mess up hardlinks and /dev
directory. I seem to remember someone advising the use of the tar command
(on the Gauteng Linux User Group list). Sort of like this.

Add new hard drive and create filesystem.
Mount new drive.
cd to new drive
Now, I don't have access to a *nix* machine at work, but it goes something
like this
tar cvfz / | tar xvfz   (but I strongly suggest you look thru the man pages
to prevent the second hard drive from being tarred too, and being passed
thru to the extract side.) (anybody got some time and a second partition to
try this?) Idea is to tar everything on old drive and feed it thru tar to
extract it onto the new drive.

run lilo - writing to new drive obviously (and equally obviously using the
kernel on the new drive).
