Apt support is optional now. Code for this has landed in trunk.

If you don't use apt then simply pass the -S / --skip-software-context option to lava-test run.

See below:

$ lava-test run --help
usage: lava-test run [-h] [-v] [-q] [-Q] [-S] [-H] [--trusted-time]
                     [--analyzer-assigned-uuid UUID] [-o FILE] [-A]
                     [-t TEST_OPTIONS]
                     test_id

positional arguments:
  test_id               Test or test suite identifier

optional arguments:
  -h, --help            show this help message and exit
  -v, --verbose         Be verbose about undertaken actions
  -q, --quiet           Be less verbose about undertaken actions
  -Q, --quiet-subcommands
                        Hide the output of all sub-commands (including tests)
  -t TEST_OPTIONS, --test-options TEST_OPTIONS
                        Override the default test options. The value is passed
                        verbatim to test definition. Typically this is simply
                        used in shell commands by expanding the string
                        $(OPTIONS). Please refer to the built-in
                        peacekeeper.py for examples. Depending on your shell
                        you probably have to escape spaces and other special
                        characters if you wish to include them in your
                        argument options.

initial bundle configuration:
  -S, --skip-software-context
                        Do not store the software context in the initial
                        bundle. Typically this saves OS image name and all the
                        installed software packages.
  -H, --skip-hardware-context
                        Do not store the hardware context in the initial
                        bundle. Typically this saves CPU, memory and USB
                        device information.
  --trusted-time        Indicate that the real time clock has accurate data.
                        This can differentiate test results created on
                        embedded devices that often have inaccurate real time
                        clock settings.
  --analyzer-assigned-uuid UUID
                        Set the analyzer_assigned_uuid to the specified value.
                        This will prevent the test device from attempting to
                        generate an UUID by itself. This option may be
                        required if the test device has unreliable real time
                        clock (no battery backed, not ensure to be up-to-date)
                        and unreliable/random hardware ethernet address.

complete bundle configuration:
  -o FILE, --output FILE
                        After running the test parse the result artifacts,
                        fuse them with the initial bundle and finally save the
                        complete bundle to the specified FILE.
  -A, --skip-attachments
                        Do not store standard output and standard error log
                        files as attachments. This option is only affecting
                        the bundle created with --output, the initial bundle
                        is not affected as it never stores any attachments.
