Hi , 

What are the points to be observed while writing custom init 
 
I am currently doing something like :  
/* 
  1.  never exit 
   2. open fd 0,1 & 2 
   3. link statically  */

int main( int argc, char **argv )
{
int fd ;
char cmd[128] = {0};

fd = open( "/dev/console", O_RDWR );
dup(fd);
dup(fd);

 while( 1 ) {
 printf( "comm>" ); fflush( stdout );
 fgets( cmd, sizeof(cmd ), stdin );

 if( memcmp( "init", cmd , 4 ) == 0 ) 
   { close(0); close(1);close(2); execv("/init/sbin", argv ); }

 if( memcmp( "quit", cmd, 4) == 0 ) reboot( RB_AUTOBOOT );
 } /* while */

/* should not reach here */
return 0 ;
}


Am I missing something ?

Thanx & Regards 
soumen
