libwaive is a single-file C (~300 LOCs [1]) source code library, I glanced over
it and it looks straightforward enough. I compared it to the seccomp manpage
[2] code samples and saw nothing suspicious.

I think it may not have been updated for newly added syscalls, but that
should not make it unsecure, mainly because what is not explicitely allowed
is prevented from use (default-locked policy [3]).

So, I'll wait for a bit more feedback before working on this, but I think
it may still be a worthwhile addition.

WDYT ?
