<jmd>I don't think in this case there is anything in the log file to help me. But which 2 log files would I compare anyway?
<methalo>one is the generated by guix, and the other generated manually, or misunderstand the question :)
<jmd>???So what you are suggesting is that I manually create log file using some unconcous knowledge of what the pertinent difference is, then use diff to compare with the guix geneated logfile to expose that knowlegdge ?
<methalo>Sometimes I check the value of the variables and find differences
