[GitHub] [couchdb-pkg] nickva opened a new pull request, #99: Improve /dev/random usage when generating cookies for RPM distros
nickva opened a new pull request, #99:
URL: https://github.com/apache/couchdb-pkg/pull/99
In a low entropy environments, `/dev/random` will block, so make sure to use only as many bytes as we'll need instead of reading and discarding bytes as we did previously.
Thanks to @lostnet for the `dd` idea and to @Inperpetuammemoriam for reporting the issue in https://github.com/apache/couchdb-pkg/pull/98
