Created attachment 764995 [details] strace
Hm, you might need to use strace -f? It exits happily, it.. seems, after calling clone?
Created attachment 765329 [details] strace -f rseq?
Created attachment 765330 [details, diff] ntpsec-1.2.1-seccomp-rollup looks like it was that one yes, works for me now with fixed patch.
Created attachment 765478 [details, diff] fixed patch slightly fixed patch, since chrony does it like this, someone should check before applying.
