It takes the directory name as a parameter.  Take a look in /etc/rc.

Boy, that *is* full.  Not even space for a directory block.

The high-intensity messages are generated by the kernel.  But what do
you mean "something similar"?  Do you mean, can you put your /tmp file
system elsewhere?  Yes, you can.  Just do this:

# mkdir /home/tmp
# mv /tmp /TMP
# ln -s /home/tmp /tmp

At some later time, when you're sure you don't need anything in /TMP,
you can remove it and its contents.
