I agree with Andraž here, they should not be tmpfs by default.
IMHO the best thing would be to add them commented out.
When installing smgl there are already lots of things to think about and
it's quite easy to forget to disable tmpfs in fstab.

Besides the FHS, not everyone has the option to install all the RAM they
ever need...
Take my own laptop as an example, I really do need to be carefull with
the 320MB RAM in there (it's a hardware limit).
