On my sparc for bootroot directory ('du' there give me 109mb but I know
that on zfs the disk usage is less than the sum of the file sizes)
bootroot_archive.py calculate boot_root_size as 109mb before
ti_create_target, tunefs and compression,
root_archive - 68mb before mkfile, lofiadm,newfs and compression
processes.
root_archive give me smaller miniroot.
