Summary
We've noticed that the latest Alpine-based nginx (1.31.3-alpine) fails to start in
Guardian containers on one of our Cloud Foundry installations because musl libc now uses pwritev2 to write the PID file. However this syscall is blocked by the current seccomp profile.
preadv2andpwritev2have been introduced in Linux 4.6 and aremodern equivalents of preadv/pwritev.
