I didn't save my original init/main.c so I can't make you a diff. Easy
temp fix though, others will find a better way.

A few lines from the end of the file (line 1014) is:

execve(execute_command,argv_init,envp_init);

Just add:
if(execute_command != NULL)
if(*execute_command)
execve(execute_command,argv_init,envp_init);

That'll fix it.

Cheers,
