  No true.
  1) this is vulnerable to /bin/sh disappearing, bring broken, etc.
  2) the script can be killed

  As pid=1, if init dies, the system dies. 

  Some people want to build systems that are too small to have /bin/sh.
I've seen lots of Xenix 286 systems like this as POS terminals.
  Other than that, I agree with you.
