Removing /tmp and replacing it with a link is a bad idea, it might have 
unexpected effects if you have to go into single user mode for 
maintenance - especially if /usr cannot be mounted at that time. A 
solution would be to create a /usr/tmp BEFORE mounting /usr

If the problem comes from locate, the best option is to move locate 
database and temp files on another drive - take a look at locate.rc for 
information - this should cause 0 downtime.

If the problem is that the tmp file is really too small for a number of 
operation including locate (for example compile also fails due to lack 
of space) you will need to either configure each and every failing 
program to use a different temp directory or move temp directory
