You were most likely not paying attention and copied something into
your root partition, or you were mistakenly running as the root user
all the time. Also, you seem to be confusing your root partition
"/dev/wd0a" which contains your root file system "/", with the home
directory of the root user "/root/"
After a normal installation, you'll have the following in /
$ ls -laF /
total 41924

I've you've copied a bunch of crap into any of the following
directories:
/
/altroot/
/bin
/dev/
/etc/
/root/
/sbin/
/stand/
then you'll run out of space on the root partition. If you don't have
a bunch of unwanted files directly under / then you'll need to figure
out under which directory you put all the crap.
Though it will take a while to run, the following command will show you
how many kilobytes is being used by each directory. This must be run as
root for it to work.
# find -x / -type d -maxdepth 1 -print0 | xargs -0 du -ksx | sort -n
2 /altroot
2 /mnt
2 /stand
16 /root
40 /dev
58 /tmp
4606 /bin
7632 /etc
11574 /sbin
14144 /var
44794 /
472530 /usr
25284058 /home
On occasion you *need* to use the root account temporarily, but you
should *NOT* be running as the root user all of the time. The home
directory of the root user, namely "/root/" should always look about
like this.
$ sudo ls -laF /root/
total 32
drwx------ 3 root wheel 512 Mar 2 12:00 ./
drwxr-xr-x 15 root wheel 512 Mar 7 19:04 ../
-rw-r--r-- 1 root wheel 22 Nov 10 06:58 .Xdefaults
-rw-r--r-- 1 root wheel 578 Nov 10 06:58 .cshrc
-rw------- 1 root wheel 125 Nov 10 06:58 .klogin
-rw-r--r-- 1 root wheel 328 Feb 11 10:42 .login
-rw-r--r-- 1 root wheel 411 Nov 10 06:58 .profile
drwx------ 2 root wheel 512 Nov 20 13:46 .ssh/
$
If you've made the mistake of running as the root user, then you've
probably got a ton of crap under /root/ which has caused you to run out
of space on the root partition.
