IMHO this can be safely disabled, as there is little if any need to debug
userspace programs _that_ deeply on an IPFire machine.

To prevent exhaustion of server resources by a maliciously
configured domain, the number of recursive queries that can be
triggered by a request before aborting recursion has been further
limited. Root and top-level domain servers are no longer exempt from
the max-recursion-queries limit. Fetches for missing name server
address records are limited to 4 for any domain. This issue was
disclosed in CVE-2020-8616. [GL #1388]
Replaying a TSIG BADTIME response as a request could trigger
an assertion failure. This was disclosed in CVE-2020-8617. [GL

Feature Changes
Message IDs in inbound AXFR transfers are now checked for
consistency. Log messages are emitted for streams with inconsistent
message IDs. [GL #1674]
Bug Fixes
When running on a system with support for Linux capabilities, named

causing a spurious log message, "unable to set effective uid to 0:
Operation not permitted", which has now been silenced. [GL #1042]

random: Initialise the kernel's PRNG earlier
Since more processes depend on good randomness, we need to
make sure that the kernel's PRNG is initialized as early as
possible.
For systems without a HWRNG, we will need to fall back to our
noisy loop and wait until we have enough randomness.
This patch also removes saving and restoring the seed. This
is no longer useful because the kernel's PRNG only takes any
input after it has successfully been seeded from other sources.
Hence adding this seed does not increase its randomness.
