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.

907 Linux kernels >= 2.6.24 support unlimited loopback devices. They are
908 allocated for use when trying to use a loop device. The loop device
909 must however exist.

911 This feature lets mount to try to create next /dev/loopN device
912 if it does not find a free one.

Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]920 Historically, Unix systems kept track of the currently mounted
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000[diff] [blame]921 partitions in the file "/etc/mtab". These days, the kernel exports
Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]922 the list of currently mounted partitions in "/proc/mounts", rendering
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000[diff] [blame]923 the old mtab file obsolete. (In modern systems, /etc/mtab should be
Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]924 a symlink to /proc/mounts.)

Rob Landley6a6798b2005-08-10 20:35:54 +0000[diff] [blame]926 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 +0000[diff] [blame]932 by --bind or --move mounts, won't update if you rename a directory
Bernhard Reutner-Fischer3e8669f2008-07-22 18:27:53 +0000[diff] [blame]933 that contains a mount point, and so on. (In brief: avoid.)
Rob Landley17507fa2006-05-08 02:22:24 +0000[diff] [blame]934
935 About the only reason to use this is if you've removed /proc from
936 your kernel.
