Perhaps rewording tmpfs(5) to say “If this is explicitly set to the
empty string, the kernel default…” is in order?
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.
