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.

Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000[diff] [blame]829 When you want to remove a mounted filesystem from its current mount
830 point, for example when you are shutting down the system, the
831 'umount' utility is the tool to use. If you enabled the 'mount'
832 utility, you almost certainly also want to enable 'umount'.

Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]849 Enabling this feature allows automatic mounting of files (containing
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000[diff] [blame]850 filesystem images) via the linux kernel's loopback devices.
851 The mount command will detect you are trying to mount a file instead
852 of a block device, and transparently associate the file with a
853 loopback device. The umount command will also free that loopback
854 device.

Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]867 Historically, Unix systems kept track of the currently mounted
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000[diff] [blame]868 partitions in the file "/etc/mtab". These days, the kernel exports
Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]869 the list of currently mounted partitions in "/proc/mounts", rendering
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000[diff] [blame]870 the old mtab file obsolete. (In modern systems, /etc/mtab should be
Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]871 a symlink to /proc/mounts.)

Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]873 The only reason to have mount maintain an /etc/mtab file itself is if
874 your stripped-down embedded system does not have a /proc directory.
875 If you must use this, keep in mind it's inherently brittle (for
876 example a mount under chroot won't update it), can't handle modern
877 features like separate per-process filesystem namespaces, requires
878 that your /etc directory be writeable, tends to get easily confused
Rob Landley17507fa2006-05-08 02:22:24 +0000[diff] [blame]879 by --bind or --move mounts, won't update if you rename a directory
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000[diff] [blame]880 that contains a mount point, and so on. (In brief: avoid.)
Rob Landley17507fa2006-05-08 02:22:24 +0000[diff] [blame]881
882 About the only reason to use this is if you've removed /proc from
883 your kernel.
