This tool reads modules.devname from the current kernel directory and outputs
the information. By default in a human-readable format, and optionally in
machine-readable formats.
For now only the tmpfiles.d(5) format is supported, but more could easily be
added in the future if there is a need.
This means nothing but kmod needs to reads the private files under
/lib/modules/. In particular systemd-udevd can stop reading modules.devname.
Tools that used to read /lib/modules/`uname -r`/modules.devname directly, can
now move to reading 'kmod static-nodes devname'.
Only the public header maintains #ifndef in the header, together with
pragma. The other ones contain only pragma.
As reported by Shawn Landden on systemd mailing list this is compatible
with all major compilers and gcc has this since version 3.3.
If using libtool 2.4.2, running the script generated by libtool will not
work because libtool changes argv[0] to lt-progname.
To test this is necessary to either fix the installed
build-aux/ltmain.sh file or run the binary directly like in:
$ export LD_LIBRARY_PATH=$PWD/libkmod/.libs/
$ ./tools/.libs/kmod help
