Thus, as tar uses /tmp, the / filesystem fills up and I cannot
continue. How can I specify a tmp directory for tar in my home
directory? Note that man tar makes no mention of a tmp option.

Boot in single user mode, Then as root:

# mkdir /home/tmp
# chmod 777 /home/tmp
# mv /tmp /tmp-old
# ln -s /home/tmp /tmp
# cp -a /tmp-old/* /tmp

That creates a /home/tmp directory, allows everyone access, renames the
old /tmp to /tmp-old, symlinks /home/tmp to /tmp, then copies everything
that was in the old /tmp to the new one. Once that's done, you can
reboot and all references to /tmp will now access /home/tmp.

Thanks, Rick, I'll try that. I can then simply erase the symlink? I
know that "rm /tmp" will not erase the symlink, rather the content of
/home/tmp so how can I remove it afterwards? Thanks.

Also, as a learning experience, is there a way a user without root
access could unpack the tar? It's not a problem, but I'd like to
learn. Thanks.
