main/nfs-utils: `/etc/init.d/nfs stop` always failed

Package Information

• Package name: nfs-utils
• Package version: 2.6.4-r2
• Alpine version: 3.21.0_alpha20240923
• Alpine architecture: x86_64

Summary

The init script attempts to stop the nfsd kernel thread using signal 2 (SIGINT), but has no effect. Which causes /etc/init.d/nfs stop always failed.

I checked git logs, it commited at 0539ae2c for update OpenRC services from Gentoo.

Gentoo already fixed this issue by https://gitweb.gentoo.org/repo/gentoo.git/commit/net-fs/nfs-utils/files/nfs.initd?id=7aa183ae8073593cab6d3f012a981a6e6712ffc2

I think this issue also affects 3.20-stable

Steps to reproduce

1. apk add nfs-utils
2. /etc/init.d/nfs start && /etc/init.d/nfs stop
