看這個信息,我的Android設備是較大的Flash,它使用內置的SD卡。我不能喜歡它的設備節點,並且不知道它是文件系統類型。Android內置SD設備節點和文件系統類型?

廣東話」喜歡設備節點。
讓我們來看看其他設備沒有內置SD:
/ # ls /dev/block/mmcblk0
/dev/block/mmcblk0
/# fdisk /dev/block/mmcblk0
The number of cylinders for this disk is set to 80672.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): p

哪裏是設備節點內置的SD?哪種類型是文件系統?
