    mkinitrd(8): determine the initrd size from the contents size
    
    * Calculate the contents size to determine the required initrd size.
    
      The used initrd size is determined from the total contents size, rounded up
      to align with 1 MiB, added additional 1 MiB.
    
      The calculated initrd size is 12 MiB at the moment, so we have 3 MiB
      more usable memory now (compared to the fixed 15 MiB before).
    
    * Add options "-s" to specify the required initrd size as before.  But a check
      against the above determined required initrd size is performance to avoid the
      out-of-space error, resulting in a broken initrd image.
    
    * Add option "-S" to constrain the allowed maximum initrd size, because a too
      big initrd image will also lead to boot failure, due to the boot loader
      limitation.
    
    * Some minor cleanups and improvements, better error handle and messages.
    
    * Update the mkinitrd.conf and man page accordingly.
