 I can not reproduce it with the regular installed sysinst. There is nothing
 magic sysinst does about the kern set, and the only special post extraction
 action in x86 MD parts of sysinst is to copy /usr/mdec/prekern to /.
 
 That is: sysinst (when upgrading) does extract kern-GENERIC, but does
 not play any games with the names.
 
 I do, however, see exactly the same symptom (as mrg pointed out already)
 during extraction for a short time, when tar extracts the file it will
 do so to a temporary filename and then rename it into place.
 
 Whatever happens for you sounds like a tar issue to me - and we have seen
 elsewhere recently that tar or extractor failures do not always propagate
 through progress(1) - maybe there is some failure and we are not told
 about it?
