Not quite - init is the built in module which starts up erlang. Source  
code is in the kernel app.

It seems that that Erlang is failing in trying to execute this thing:

exit(list_to_atom(concat(["cannot expand \$", Var, " in bootfile"])))

It suggests that something in the path element of the boot file is not  
correct.

There also appears to be a bug in the error handling for this case.

You're not doing anything strange like using a boot file created with  
R10B in an R9 node or something strange? I had the impression there  
were some changes in the format of the parameters provided to init  
recently.

Good Luck
