I'll chime in on the reason for this.
In the current state, the pdns-recursor package in Xenial is not fit for
production use (let alone inclusion in an LTS). Several of the issues
include:
- Configuring forwarding results in SIGABRT (fixed in
https://github.com/pieterlexis/pdns/commit/88490c0365375978afea38bf352079b4fef28e17)
- RPZ and IXFR with TSIG is broken (fixed in
https://github.com/pieterlexis/pdns/commit/bd051ad662f10373bb8f3e13a55cbec3f6ebc91c
and
https://github.com/pieterlexis/pdns/commit/f0ca9bcf2800bb31513283bbe9fa5d1e2b83dcf6)
- The cache would fill the memory with stale entries (fixed in
https://github.com/rgacogne/pdns/commit/2b94bb415eb33d909e064cadea06a7c2fcea7380)
Combined with the fact that DNSSEC validation has many broken
cornercases in Alpha 1 and Alpha 2 (but the Debian package has disabled
the validation as per our recommendation), we believe that the package
suggested is many times better than the package currently in Xenial.
We released this Alpha 2 because of the Ubuntu freeze, as Ubuntu
originally pulled in the Alpha 1 from Debian Sid. We contacted devel-
discuss, but got little response regarding our suggested solutions
(https://lists.ubuntu.com/archives/ubuntu-devel-
discuss/2016-February/016183.html).
I hope this answers your questions regarding why we'd like a freeze
exception. The only other solution (in our eyes as upstream) is to have
Xenial revert to the Recursor 3.7.3, which might go EOL before Xenial
does.
Best regards,
Pieter Lexis
