Datasource dsname
*****************

Each datasource has an attribute called dsname. This may be used in the
kernel commandline to
:ref:`override datasource detection<kernel_datasource_override>`. The
``dsname`` on the kernel command line may be a case-insensitive match. See the
mapping between datasource module names and ``dsname`` in the table below.


..
    generate the following map with the following one-liner:

    find cloudinit/sources -name 'DataSource*.py' \
    |  xargs grep 'dsname =' \
    | awk -F '[/:"]' 'BEGIN { print "**Datasource Module**, **dsname**" }\
      {print $3 ", " $5}'
