I found it confusing as well, which is why I tracked this down. To “provide no value” you have to actually do… TMPFS_SIZE= … in /etc/defaults/tmpfs because the commented-out value is default. Perhaps rewording tmpfs(5) to say “If this is explicitly set to the empty string, the kernel default…” is in order?
