--test [<uname -r output> rpm|dpkg [<base expected> <versioned expected>]]]
This script tests whether a Linux system is set up to build kernel modules,
and if not prints a guess as to which distribution packages need to be
installed to do so, and what commands to use. It uses the output of the
"uname -r" command to guess the packages and searches for packaging tools
by checking for packaging databases.
For testing you can specify the output of "uname -r" which will be used
instead of the real one and the package type, and optionally the expected
output. --test without parameters will test a number of known inputs.'
# General theory of operation (valid Nov 19 2016): we check whether this is an
# rpm or dpkg system by checking for the respective non-empty database directory
# (we assert that only one is present), and based on that we map uname -r output
# to a kernel package name. Here is a textual description of known mappings
# (not all of these are currently implemented) for both the general package name
# and the version-specific package name. Keeping this here as it took some time
# and pain to research.
