411 | The mkswap utility is used to configure a file or disk partition as
|
---|
412 | Linux swap space. This allows Linux to use the entire file or
|
---|
413 | partition as if it were additional RAM, which can greatly increase
|
---|
414 | the capability of low-memory machines. This additional memory is
|
---|
415 | much slower than real RAM, but can be very helpful at preventing your
|
---|
416 | applications being killed by the Linux out of memory (OOM) killer.
|
---|
417 | Once you have created swap space using 'mkswap' you need to enable
|

418 | the swap space using the 'swapon' utility.

525 | The switch_root utility is used from initramfs to select a new

529 | Booting with initramfs extracts a gzipped cpio archive into rootfs

531 | or unmounted*, pivot_root will not work from initramfs. Instead,

532 | switch_root deletes everything out of rootfs (including itself),

595 | Historically, Unix systems kept track of the currently mounted
|
---|
596 | partitions in the file "/etc/mtab". These days, the kernel exports
|
---|
597 | the list of currently mounted partitions in "/proc/mounts", rendering
|

598 | the old mtab file obsolete. (In modern systems, /etc/mtab should be
|
---|
599 | a symlink to /proc/mounts.)
|

600 |

---|
601 | The only reason to have mount maintain an /etc/mtab file itself is if

602 | your stripped-down embedded system does not have a /proc directory.

|
---|
604 | example a mount under chroot won't update it), can't handle modern
|
---|
605 | features like separate per-process filesystem namespaces, requires
|
---|
606 | that your /etc directory be writable, tends to get easily confused
|

|
---|
608 | that contains a mount point, and so on. (In brief: avoid.)

---|
609 |

610 | About the only reason to use this is if you've removed /proc from
|
---|
611 | your kernel.
