Or you can mount two instances of tmpfs, one in /tmp and another in / 
var/tmp :-)  They'll properly share the free memory.

Also see the examples in /usr/share/examples/fstab/* (or something  
like that).

FWIW, I enabled tmpfs in GENERIC a couple of days ago or so.  (I now  
have to ensure that it works fine by running the test-suite, but PR  
36848 prevents me doing that!)

Kind regards,
