Thanks for the clarification. I think that reduces this bug to "Why is my 
tmpfs set to 20% of physical RAM rather than 20% of total virtual memory?" 
(And the rewording of the manual page would be nice too.)

I've now tried uncommenting the default TMPFS_SIZE line, and that makes no 
difference. An empty value does give 50% of physical RAM, as expected based 
on Thorsten's explanation.
