だれか 個猫に説明 してくれないだろうか？ 英語英語英語！ 勝手な解釈を しておきます。

The hmount command mounts the partition so the other commands can work with it. The hcopy command copies the yaboot program to the USB drive. Its -r option means copy raw; no conversion takes place. The colon is the HFS root directory. HFS uses colons where Linux uses slashes. The first hattrib commands sets the attributes of the yaboot program. The tbxi code is a special code used by Apple to signify that the program is the bootloader program. There should be only one of these on a device. The second hattrib commands blesses the root directory. I'm not sure what this means but it is required for the device to boot. Finally, the humount dismounts the partition. ....

また 次のような 確認もしておきました。容量について
# hformat /dev/sda2 Volume name is "Untitled" Volume was created on Sun Nov 20 21:48:41 2011 Volume was last modified on Sun Nov 20 21:48:41 2011 Volume has 206427648 bytes free # hmount /dev/sda2 Volume name is "Untitled" Volume was created on Sun Nov 20 21:48:41 2011 Volume was last modified on Sun Nov 20 21:48:41 2011 Volume has 206427648 bytes free
当然 ここまで同じでしょう でも mount はされていないようです （ここで いう mount はどういうものか はおいといて ）
# df Filesystem 1K-blocks Used Available Use% Mounted on /dev/hda15 13388696 3828816 8879772 31% / tmpfs 320844 0 320844 0% /lib/init/rw udev 315784 236 315548 1% /dev tmpfs 320844 0 320844 0% /dev/shm
書き込んだ後で 再度確認すると 当然 yaboot の容量 189996 位少なくなっ ている筈 なんですが 如何でしょうか？
# hmount /dev/sda2 Volume name is "Untitled" Volume was created on Sun Nov 20 21:48:41 2011 Volume was last modified on Sun Nov 20 22:08:41 2011 Volume has 206234112 bytes free # humount
勘違いですか 合わないな？？
206427648-189996=206237652
まあ 良く理解 していないので 追求は これ以上 止めておきまあーす！
にゃんたろう 拝！
