For the record: no, you don't need that. You can just re-exec with entire
command line intact. -b option will be seen again, and re-exec will be
seemingly done again... but second re-exec will actually NOT be done
because of this:
void forkexit_or_rexec(char **argv)
{
pid_t pid;
/* Maybe we are already re-execed and come here again? */
if (re_execed) <===================
return; <===================
The magic is in re_execed variable. grep for it.
BTW does current svn work for you?
