diskd - disk daemon; wait for disk to be inserted
This manpage has been automatically generated from fdutils’s texinfo
documentation. However, this process is only approximative, and some
items, such as crossreferences, footnotes and indices are lost in this
translation process. Indeed, these items have no appropriate
representation in the manpage format. Moreover, only the items
specific to each command have been translated, and the general
information about fdutils has been dropped in the manpage version.
Thus I strongly advise you to use the original texinfo doc.
* To generate a printable copy from the texinfo doc, run the
./configure; make dvi; dvips fdutils.dvi
* To generate a html copy, run:
./configure; make html
A premade html can be found at:
* To generate an info copy (browsable using emacs’ info mode),
./configure; make info
The texinfo doc looks most pretty when printed or as html. Indeed, in
the info version certain examples are difficult to read due to the
quoting conventions used in info.
The diskd command has the following syntax:
diskd [-d drive] [-i interval] [-e command]
Diskd waits for a disk to be inserted into a given drive, and then
either executes the command or exits. This program can be used to
automatically mount a disk as soon as it is inserted.
This program works by switching the motor on for a very short interval,
and then seeking to track -1. This might damage hardware in the long
run. Amigas, which also use these techniques, are known for having
problems with their disk drives no longer spinning up properly after a
few month of usage.
Selects the drive to observe for disk insertion. By default,
drive 0 (/dev/fd0) is observed.
Selects the polling interval. The interval is given in tenths of
seconds. Default is 10 (one second).
Gives the command to be executed when a disk is inserted. If no
command is given the program simply exits. Typically, the
command mounts the disk. It can be a shell scripts which probes
for several filesystems and disk geometries until it succeeds.
* Automatic unmounting cannot yet be handled. It is indeed not
enough to scan for disk removal, because when the disk is
removed, it is already too late: There might be some buffers
needing flushing. However, the fdmountd program allows
automatic unmounting by using the SYNC mount options, which
switches off write buffering (see section fdmount).
* The drive motor is running all the time, and on some computers,
the drive led flickers at each time the drive is polled.
