Wikipedia has related information at File system. A common feature in Unix-like filesystems is that all files appear in one file hierarchy.
The filesystem storing the base of the hierarchy is referred to as the root filesystem. Here files representing physical, and virtual devices can be accessed. Each disk or storage medium may contain one or more filesystems, each of which contains files which can contain data. Some disks are also used for swapwhich supplies a temporary storage space for data in memory, when memory is full.
Though "swap" resides on a disk, it is not actually a filesystem. The choice of Unix-like system influences the choice of filesystem.
There are two kinds of filesystems:. The chapter Partitioning Disks describes the formats in more detail and how to edit the partition maps. Then the mount command is:. The user mounts are mounting and unmounting of filesystems by users other than the superuser. Unfortunately, the different Unix variants have different approaches to this task.
An alternative is to configure "sudo" to linux mount nodes option trading users to become root when mounting and unmounting. Here are some ways that root can permit linux mount nodes option trading mounts:.
Normally, filesystems are mounted on empty directories. If the directory was not empty, its files are hidden until the filesystem is unmounted. The union mount allows these files to show through.
Each existing file from the directory only shows if there is no file in the same place on the mounted filesystem. All new files are made linux mount nodes option trading the mounted filesystem. Note that union mounts are strange and might not work well on your system.
Some operating systems provide a mount 8 option -o union for this. A filesystem can be stored on a file on another filesystem. Such files are called disk images and they have several applications:. This linux mount nodes option trading only describes raw disk images, which contain only the filesystem. Thus five steps are linux mount nodes option trading.
Association and dissociation are handled by the vnconfig 8 command. If there was no disklabel, we would instead mount partition 'c'. Some Linux kernels can mount a cloop compressed loopwhich is a compressed disk image.
Such an image must be mounted read-only. One first prepares the image and then compresses it how? Then one mounts it how? The Knoppix livecd uses a cloop to fit more programs to the CD. Here is an example. Then we use mkfs. FIXME is this correct? This is solved with vnconfig 8. If we wanted to partition the disk image, we would also have made a disklabel. One can ignore the imaginary disk geometry.
Because OpenBSD has integrated crypto, one would expect that there is a way to have an encrypted filesystem. OpenBSD only provides Blowfish encryption for disk images. This is possible with the -k flag to vnconfig 8used with -c. Note that if you entered the wrong encryption key, vnconfig will still succeed. The mount will fail because the disklabel and filesystem header are not readable.
In this case, you must vnconfig -u and then vnconfig -ck with the correct key. Make sure to use the correct key when initially formatting a new disk image. To have an entire encrypted disk partition, create a normal unencrypted disk image, mount it, then fill the partition with one large file to serve as the disk image.
Some Linux kernel configurations let you use losetup to encrypt disk images. Think of lo opback setup, not of lose tup. From Wikibooks, open books for an open world.
