The /boot directory is only used by the host system during the machine 
boot process to load the kernel. Jails do not do this as they run under 
the hosts kernel. I believe ezjail does not create this /boot directory 
in the basejail for that reason.

As you can see in this error message
  Installing updates...mkdir: /usr/jails/newjail//boot:
there are 2 // before boot  this is a command syntax error.

I remember this problem being talked about on this list before as a 
ezjail bug. Looks like it has not been fixed yet.

Check the jail & questions list archives for details.
