New Revision: 342635
URL: https://svnweb.freebsd.org/changeset/base/342635

Log:
  Change the way efibootmgr works by specifying bootnum via -b parameter
  
  Instead of passing the bootnum to each different parameter, require users
  to specify -b when running operations that need a bootnum.
  
  This allows activation of a new boot entry at the same time it's created
  by adding -a onto the command line.
