To summarize: that function is supposed to generate a filename with a hash = based not only the filename but the contents of the file. While it makes s= ense in Guix to ignore the contribution of the filename, I believe it shoul= d still output a new filename when the contents change. Otherwise there seems to be no way for a downstream package to ensure that = it is using an up-to-date .eln variant of an .el file. I may have missed something though. Can someone in the know tell me what h= appens if you have not updated Emacs (which if I understand correctly, mean= s ELN-DIR does not change), but you do update an Elisp package, whether thr= ough Guix or through Emacs' own package managers. Will Emacs then possibly = load an old .eln?=20=20 I do not believe that user options like `load-prefer-newer` would affect it= . It would just rely on running the aforementioned function and counting on= it to output an .eln filename that does not exist if the source is newer.=
