Nope, as you see here:
3> {ok, Conf1} = file:consult("egon_server.0.1.config").
{ok,[{sys,[{lib_dirs,["/home/nick/code/"]},
          {rel,"egon_server","0.1",[kernel,sasl,stdlib,egon_server]},
          {boot_rel,"egon_server"},
          {relocatable,true},
          {profile,standalone},
          {app,egon_server,[{vsn,"0.0.1"},{debug_info,keep}]}]}]}

Kernel is included.

Regards,
Nikola
