opkg does not accept a Packages.gz file created by http://golang.org/pkg/compress/gzip/

[mgumz]

having something like this src/gz feed-name https://127.0.0.1/all/ in /etc/opkg/base_feeds.conf and using the native golang okg to gzip the content of the index file "Packages" makes opkg complaint about crc-errors after downloading.

this is strange because gzip itself is able to extract the contents of such created file just fine.

until this issue is solved the current workaround as coded in https://github.com/carosio/kellner/blob/master/gzip.go has to stay.
