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.

Rob Landley6a6798b2005-08-10 20:35:54 +0000920 Historically, Unix systems kept track of the currently mounted
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000921 partitions in the file "/etc/mtab". These days, the kernel exports
Rob Landley6a6798b2005-08-10 20:35:54 +0000922 the list of currently mounted partitions in "/proc/mounts", rendering

Rob Landley6a6798b2005-08-10 20:35:54 +0000926 The only reason to have mount maintain an /etc/mtab file itself is if
927 your stripped-down embedded system does not have a /proc directory.
928 If you must use this, keep in mind it's inherently brittle (for
929 example a mount under chroot won't update it), can't handle modern
930 features like separate per-process filesystem namespaces, requires
931 that your /etc directory be writeable, tends to get easily confused
Rob Landley17507fa2006-05-08 02:22:24 +0000932 by --bind or --move mounts, won't update if you rename a directory
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000933 that contains a mount point, and so on. (In brief: avoid.)
Rob Landley17507fa2006-05-08 02:22:24 +0000934
935 About the only reason to use this is if you've removed /proc from
936 your kernel.
