I'm trying to understand an aspect of the inner workings of my
operating system (Fedora core 2).
Could anyone explain the columns within fstab, please?
For example, the last two lines are:--
/dev/sda1 /mnt/stick auto noauto,owner 0 0
/dev/cdrom /mnt/cdrom udf,iso9660
noauto,owner,kudzu,ro 0 0
Sure thing!
The first column (fs_spec) is the device or filesystem that you want to
mount. This is usually a block device or a network filesystem.
The second column (fs_file) is where you want to mount the device.
The third column (fs_vfstype) tells mount what the filesystem type on
the device is.
The fourth column (fs_mntops) is used to specify mount options. Options
are separated with commas.
The fifth column (fs_freq) is used by the dump command to work out
whether it needs to make a backup of the filesystem.
The sixth column (fs_passno) is used by fsck to see what order
filesystems need to be checked at bootup.
Much of the above was gleaned from man fstab(5), and you'll find a whole
lot more detail in there that what's posted above.
HTH,
Lindsay
