how about in one step:
mount /device /mnt
tar cpf - . | (cd /mnt ; tar xpf -)
when moving /var i suggest being in single user mode. in multiuser mode
lots of files are open in /var. another note about tar, it won't copy
socket files correctly. it will do unix domain sockets (named pipes),
but not sockets. find /dir -type s -print will find any sockets.
as long as you don't move your / partition it's easy to test. just edit
your /etc/fstab to reflect your new layout. if it fails boot into

create a boot floppy (and make sure the boot floppy's kernel will lookto
the cdrom drive to mount /). copy the image into / . then check the
manpage for mkisofs on how to get it to use the image as a boot thingy.
