This coding is what a listing of the root file system would look like. You cannot tell that there is a logical division in partitions unless you were to run a command such as df that lists the partitions along with their associated mount points. Regardless of what the partitions and mount points are, they all work together to display as one flat directory structure that looks like the following: [root@HostB /root]# ls -l / total 145 drwxr-xr-x 2 root root drwxr-xr-x 3 root root drwxr-xr-x 15 root root drwxr-xr-x 36 root root drwxr-xr-x 3 root root drwxr-xr-x 7 root root drwxr-xr-x 2 root root drwxr-xr-x 2 root root drwxr-xr-x 4 root root drwxr-xr-x 2 root root dr-xr-xr-x 44 root root drwxr-x--5 root root 4096 1024 81920 4096 4096 4096 16384 0 4096 4096 0 4096 Jun Jun Jun Jun Jun Jun Jun Jun Jun Aug Jun Jun 17 18 18 18 17 17 17 18 17 23 18 17 08:33 05:07 05:07 05:07 08:33 08:32 08:21 05:07 08:23 1999 05:06 19:30 bin boot dev etc home lib lost+found misc mnt opt proc root Hard Disk Partition Planning and Preparation drwxr-xr-x drwxrwxrwt drwxr-xr-x drwxr-xr-x 2 8 15 17 root root root root root root root root 4096 4096 4096 4096 Jun Jun Jun Jun 17 18 17 17 08:33 05:07 08:24 08:37 sbin tmp usr var An alternate way of looking at this particular scenario would be as follows.

These choices will be keyed off the label=linux and label=dos statements in the file. 2 label=linux root=/dev/hda8 read-only other=/dev/hda1 label=dos During initialization, you might use the Tab key to display these options.

An installation expert will plan ahead and know based on experience what the drives eventually will be called and how their respective partitions will be labeled after performing the installation.
