Automount
|
|
=========
|
|
|
|
barebox supports automatically mounting filesystems when a path is first
|
|
accessed. This is handled with the :ref:`command_automount` command. With automounting
|
|
it is possible to separate the configuration of a board from actually using
|
|
filesystems. The filesystems (and the devices they are on) are only probed
|
|
when necessary, so barebox does not lose time probing unused devices.
|
|
|
|
Typical usage is for accessing the TFTP server. To set up an automount for a
|
|
TFTP server, the following is required::
|
|
|
|
mkdir -p /mnt/tftp
|
|
automount /mnt/tftp 'ifup eth0 && mount -t tftp $eth0.serverip /mnt/tftp'
|
|
|
|
This creates an automountpoint on ``/mnt/tftp``. Whenever this directory is accessed,
|
|
the command ``ifup eth0 && mount -t tftp $eth0.serverip /mnt/tftp`` is executed.
|
|
It will bring up the network device using :ref:`command_ifup` and mount a TFTP filesystem
|
|
using :ref:`command_mount`.
|
|
|
|
Usually the above automount command is executed from an init script in ``/env/init/automount``.
|
|
With the above, files on the TFTP server can be accessed without configuration::
|
|
|
|
cp /mnt/tftp/linuximage /image
|
|
|
|
This automatically detects a USB mass storage device and mounts the first
|
|
partition to ``/mnt/fat``::
|
|
|
|
mkdir -p /mnt/fat
|
|
automount -d /mnt/fat 'usb && [ -e /dev/disk0.0 ] && mount /dev/disk0.0 /mnt/fat'
|
|
|
|
To see a list of currently registered automountpoints use ``automount -l``.
