12 acpid listens to ACPI events coming either in textual form from
13 /proc/acpi/event (though it is marked deprecated it is still widely
14 used and _is_ a standard) or in binary form from specified evdevs
15 (just use /dev/input/event*).
16
17 It parses the event to retrieve ACTION and a possible PARAMETER.
18 It then spawns /etc/acpi/<ACTION>[/<PARAMETER>] either via run-parts
19 (if the resulting path is a directory) or directly as an executable.
20
21 N.B. acpid relies on run-parts so have the latter installed.

846 does a mount --move that overmounts rootfs with the new root, and

858 point, for example when you are shutting down the system, the
859 'umount' utility is the tool to use. If you enabled the 'mount'

879 The mount command will detect you are trying to mount a file instead
880 of a block device, and transparently associate the file with a
881 loopback device. The umount command will also free that loopback
882 device.

Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]895 Historically, Unix systems kept track of the currently mounted

Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000[diff] [blame]898 the old mtab file obsolete. (In modern systems, /etc/mtab should be

Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]901 The only reason to have mount maintain an /etc/mtab file itself is if
902 your stripped-down embedded system does not have a /proc directory.
903 If you must use this, keep in mind it's inherently brittle (for
904 example a mount under chroot won't update it), can't handle modern
905 features like separate per-process filesystem namespaces, requires
906 that your /etc directory be writeable, tends to get easily confused

Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000[diff] [blame]908 that contains a mount point, and so on. (In brief: avoid.)
Rob Landley17507fa2006-05-08 02:22:24 +0000[diff] [blame]909
910 About the only reason to use this is if you've removed /proc from
911 your kernel.
