--debug Output debug information of the build process
- -v, --verbose Verbose output during the build process
+ -L, --stdlog [0-6] Specify logging level (to standard error)
+ 0 - suppress any messages
+ 1 - only fatal errors
+ 2 - all errors
+ 3 - warnings
+ 4 - info (default)
+ 5 - debug info (here starts lots of output)
+ 6 - trace info (and even more)

-c, --conf [FILE] Specify configuration file to use.
Default: /etc/dracut.conf
--confdir [DIR] Specify configuration directory to use *.conf files
-i, --include [SOURCE] [TARGET]
Include the files in the SOURCE directory into the
Target directory in the final initramfs.
+ If SOURCE is a file, it will be installed to TARGET
