# Example script called by Mender agent to collect inventory data for a
|
||
|
|
# particular devce. The script needs to be located in $(datadir)/mender and its
|
||
|
|
# name shall start with `mender-inventory-` prefix. The script shall exit with
|
||
|
|
# non-0 status on errors. In this case the agent will discard any output the
|
||
|
|
# script may have produced.
|
||
|
|
#
|
||
|
|
# The script shall output inventory data in <key>=<value> format, one entry per
|
||
|
|
# line. Entries appearing multiple times will be joined in a list under the same
