4.1.8 Autocopy
This service is executed after the OS has booted and when a storage medium has been inserted. It is triggered
together with the the
Autostart
service (see chapter
[
I
) via UDEV.
Autocopy
always runs before
Autostart
.
The
Autocopy
service provides a comfortable installation and/or update functionality as well as copy mechanism
for specific files that are not included in the OS (e.g. for runtime libraries).
Subfolders and files within a folder named
autocopy
on a USB stick, SD card or in the NAND flash will be copied
to the root of the device resp. its equivalent targets. Non-existing folders will be created automatically.
The autocopy mechanism includes the following components:
/etc/udev/rules.d/automount.rules
:
UDEV rule that triggers the mount.sh script
when a storage media is plugged/unplugged
/etc/udev/scripts/mount.sh
:
Script that implements the autocopy and automount
functionality.
Example:
The user has created and application
myapp
that should be installed to
/usr/bin/myapp
on the target
and a library
mylib.so
used by this application that should be installed to
/usr/lib/mylib.so
. The layout of the
storage medium is shown in figure
