If you don't screw with the timestamps and use default compression,
(gunzip x.gz; gzip x) is idempotent. So would be:
(gunzip upstream.orig.tar.gz; bzip2 upstream.orig.tar)
[intervening operations]
(bunzip2 upstream.orig.tar.bz2; gzip upstream.orig.tar)
unless your upstream author did something really stupid (yep, I said
stupid) like add a compression level option.
As far as "pristineness" with the filenames goes, I'm not sure if I
follow your argument, which seems to indicate that we're not really
shipping "pristine" tar files (and thus it doesn't matter if we touch,
untar, recompress using zoo, randomly swap bytes...). Or am I missing
a negative somewhere?
