Petr, All,

On 2017-09-12 00:13 +0200, Petr Kulhavy spake thusly:
> Force gzip compression level 6 when calculating hash of a downloaded GIT repo.
> To make sure the tar->gzip->checksum chain always provides consistent result.`
> 
> The script was relying on the default compression level, which must not be
> necessarily consistent among different gzip versions. The level 6 is gzip's
> current default compression level.

Not only is it the _current_ default, it has always been so since the
