Subject: Use copy.deepcopy() to copy os.environ
X-Git-Tag: v16~66
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=06eaadf1213763ecd6f9edc519fd4e2cd63d0966;p=thirdparty%2Fmkosi.git

Use copy.deepcopy() to copy os.environ

Otherwise any changes we make to os.environ propagate into our
shallow copy.
