[erlang-questions] minimal failure case for specifying mnesia directory

Hi,

  Here is my minimal failure case:

https://github.com/txrev319/fail0

  This is what's going on here. When I
  * run _rel/bin/fail0 console
  * and then I type in "mnesia:info()"

  * I get /home/x/tmp/fail0/_rel/

despite putting "/home/x/data" into priv/sys.config. See:
https://github.com/txrev319/fail0/blob/master/priv/sys.config


  I'm clearly doing something retarded. What am I doing wrong?

Thanks!
