* Prevent the /boot entry from ever being renamed. You couldn't even try to

Browse Source 
switch /boot to a different volume in two operations, unless you have first
  linked /system/lib into /bin. This patch assumes that / will always have the
  ID 1. Don't know if that is proper. Note that I also thought about solving
  this in the VFS, since perhaps it isn't the job of root-fs to know about
  /boot, but that would of course introduce another check for every rename
  operation, which I decided against.
