14 acpid listens to ACPI events coming either in textual form from
15 /proc/acpi/event (though it is marked deprecated it is still widely
16 used and _is_ a standard) or in binary form from specified evdevs
17 (just use /dev/input/event*).
18
19 It parses the event to retrieve ACTION and a possible PARAMETER.
20 It then spawns /etc/acpi/<ACTION>[/<PARAMETER>] either via run-parts
21 (if the resulting path is a directory) or directly as an executable.
22
23 N.B. acpid relies on run-parts so have the latter installed.

Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]713 The only reason to have mount maintain an /etc/mtab file itself is if

716 example a mount under chroot won't update it), can't handle modern
717 features like separate per-process filesystem namespaces, requires
