OS X (Apple)

Hi All,

I am having a clarification regarding the mounted file systems on a normal mac.

This is the output displayed once i launch terminal and key in mount
command.
**************************************************

Code:

/dev/disk0s2 on / (hfs, local, journaled)
devfs on /dev (devfs, local, nobrowse)
/dev/disk0s3 on /Volumes/Mac2 (hfs, local, journaled)
map -hosts on /net (autofs, nosuid, automounted, nobrowse)
map auto_home on /home (autofs, automounted, nobrowse)

**************************************************
Here the Red ones show the file system and the blue one shows the mount points.
As per my understanding if i am in a mount point , i should be able to see the file system.
Say
pwd is root
/
then i am able to do "cd /dev/disk0s2"
ie i am able to see the file system /dev/disk0s2 from /
But if i am in the mount point
/Volumes/Mac2
then i am unable to see any file system
/dev/disk0s3

Is there anything different here?

/dev/disk[whatever] are device files -- files the kernel uses to access the physical device. This physical device is then mounted to a filesystem that you can use.

You can't

Code:

 cd /dev/disk0s2

because it's a device file.

Think of it a gateway to the hardware.

devfs, as I understand it, is a true device driver. It makes the /dev entries that the kernel uses.

The "map" entries are used by the automounter.

Everything looks normal.
