Let's say we run
df command to show something about file system in my CentOS.
I can see a LVM
/dev/mapper/vg_centos64-lv_root mount to
/. or a partition
/dev/sda1 mount to
/boot, and a device CDROM
/dev/sr0 mount to
And I can see them(filesystem) in the
Nautilus. They either looks like a
directory. Please looks below.
For my point of view. It is really confused that blending all the things(I mean the thing like partition
sda1 and the things like device
sr0) into the filesystem. And what the
Mount doing looks like pointing a "file" to another "directory". So It really looks like that the same thing has 2 addresses to be accessed. Why does the Linux file system design like this? And Please correct me if there is something wrong with what I thought. Thanks.
I Also want to know Whether I should access from the file system or Mount point if I want? Because both are pointing to the same things.
