We better go back a review filesystems here. When most kernels boot they initialize the system by automatically mounting root and they fire up init and a few other processes. At this point, the only thing mounted is root:
/dev/dsk/c0t0d0s0 1987399 935141 992637 49% /
If you are going into single user mode, it stops here and that is all you see. If you examined /var or /usr you would only have empty directiores since they are not yet mounted. All of the subdirecties and files that we do see are on /dev/dsk/c0t0d0s0.

But we have another disk device called c0t0d0s3 which we can now mount on /var. Once we do that we suddenly see /var/spool spring into existence. But /var/spool is on c0t0d0s3 while /etc/mail is on c0t0d0s0. They may seem to equally situated in some respects, but the difference is important.

Most people also will have a separate /usr filesystem. Looking again, I see that you don't. So I misspoke earlier when I said that you also needed /usr. In your case, you don't. You could possibly configure your system to only have one very large root filesystem...if you did, one ufsdump would do it all.

When you tell ufsdump to save a copy of c0t0d0s0, that is what it does. Sure it will pick up the /var empty directory that root uses as a mount point, but nothing under /var will be there. That's why we need another run of ufsdump to also save a copy of c0t0d0s3.
