162 Part II . Running the Show . Field 5 The number in this field indicates whether the indicated file system needs to be dumped (that is, have its data backed up). A 1 means that the file system needs to be dumped, and a 2 means that it doesn t. (I don t think this field is useful anymore because many Linux systems no longer include the dump command. Most often, a 0 is used.) . Field 6 The number in this field indicates whether the indicated file system needs to be checked with fsck: 1 means it needs to be checked, and 2 means it doesn t. If you want to add an additional local disk or partition, you can create an entry for it in the /etc/fstab file. See Chapter 27 for information on mounting Samba, NFS, and other remount file systems from /etc/fstab. Using the mount Command to Mount File Systems Linux systems automatically run mount -a (mount all file systems) each time you boot. For that reason, you generally use the mount command only for special situations. In particular, the average user or administrator uses mount in two ways: . To display the disks, partitions, and remote file systems currently mounted. . To temporarily mount a file system. Any user can type mount (with no options) to see what file systems are currently mounted on the local Linux system. The following is an example of the mount command. It shows a single hard disk partition (/dev/hda1) containing the root (/) file system, and proc and devpts file system types mounted on /proc and /dev, respectively. The last entry shows a floppy disk, formatted with a standard Linux file system (ext3) mounted on the /mnt/floppy directory. $ mount /dev/hda3 on / type ext3 (rw) /dev/hda2 on /boot type ext3 (rw) /dev/proc on /proc type proc (rw) /dev/sys on /sys type sysfs (rw) /dev/devpts on /dev/pts type devpts (rw,gid=5,mode=620) /dev/shm on /dev/shm type tmpfs (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) /dev/hdc on /media/cdrecorder type iso9660 (ro,nosuid,nodev) /dev/fd0 on /mnt/floppy type ext3 (rw) Traditionally, the most common devices to mount by hand are your floppy disk and your CD drive. However, depending on the type of desktop you are using, CDs and floppy disks may be mounted for you automatically when you insert them. (In some cases, the autorun program may also run automatically. For example, autorun may start a CD music player or software package installer to handle the data on the medium.)
