- Generate a link to the initramfs file with an appropriate file extension, guessed based on the compressor by default - Use correct metadata in u-boot images if generated, up to now this was hardcoded to gzip and would silently generate an erroneous image if another compressor was specified - Document all the parameters - Improve cross-building compatibility, by allowing passing either a string as before, or a function taking a package set and returning the path to a compressor in the "compressor" argument of the function. - Support more compression algorithms - Place compressor executable function and arguments in passthru, for reuse when appending initramfses Co-Authored-By: Dominik Xaver Hörl <hoe.dom@gmx.de>
