Package: release.debian.org Severity: normal User: release.debian....@packages.debian.org Usertags: unblock
Please unblock the bird package because the version in testing has some serious bugs about routes propagation, better explained in the attached diff. This was discussed in #928141, where one of the upstream maintainers recommended that 1.6.6 should get into testing. The version currently in unstable has been in unstable for three months without any issues, and is the one that I am using in production (while the one currently in testing was toxic in my environment). I am not the bird maintainer, but Ondřej looks busy and I am sure that he will not mind me requesting this. I am attaching a debdiff from which I removed the generated files and some documentation/example changes not relevant for the Debian package. unblock bird/1.6.6-1 -- ciao, Marco
