21 (just use /dev/input/event*).
22
23 It parses the event to retrieve ACTION and a possible PARAMETER.
24 It then spawns /etc/acpi/<ACTION>[/<PARAMETER>] either via run-parts
25 (if the resulting path is a directory) or directly as an executable.

639 bool "switch_root"

641 help
642 The switch_root utility is used from initramfs to select a new
643 root device. Under initramfs, you have to use this instead of
644 pivot_root. (Stop reading here if you don't care why.)
645
646 Booting with initramfs extracts a gzipped cpio archive into rootfs
647 (which is a variant of ramfs/tmpfs). Because rootfs can't be moved
648 or unmounted*, pivot_root will not work from initramfs. Instead,
649 switch_root deletes everything out of rootfs (including itself),
650 does a mount --move that overmounts rootfs with the new root, and
651 then execs the specified init program.
652
653 * Because the Linux kernel uses rootfs internally as the starting
654 and ending point for searching through the kernel's doubly linked
655 list of active mount points. That's why.

681 Enabling this feature allows automatic mounting of files (containing
682 filesystem images) via the linux kernel's loopback devices.
683 The mount command will detect you are trying to mount a file instead
684 of a block device, and transparently associate the file with a
685 loopback device. The umount command will also free that loopback
686 device.
687
688 You can still use the 'losetup' utility (to manually associate files
689 with loop devices) if you need to do something advanced, such as
690 specify an offset or cryptographic options to the loopback device.
691 (If you don't want umount to free the loop device, use "umount -D".)

709 select BUSYBOX_CONFIG_FEATURE_MOUNT_FAKE
710 help
711 Historically, Unix systems kept track of the currently mounted
712 partitions in the file "/etc/mtab". These days, the kernel exports
713 the list of currently mounted partitions in "/proc/mounts", rendering
714 the old mtab file obsolete. (In modern systems, /etc/mtab should be
715 a symlink to /proc/mounts.)
716
717 The only reason to have mount maintain an /etc/mtab file itself is if
718 your stripped-down embedded system does not have a /proc directory.
719 If you must use this, keep in mind it's inherently brittle (for
720 example a mount under chroot won't update it), can't handle modern
721 features like separate per-process filesystem namespaces, requires
722 that your /etc directory be writable, tends to get easily confused
723 by --bind or --move mounts, won't update if you rename a directory
724 that contains a mount point, and so on. (In brief: avoid.)
725
726 About the only reason to use this is if you've removed /proc from
727 your kernel.
