내가 생각한 원인

net.enp1s0의 준비가 완료되기 전에 nfs mount를 시도해서 실패하는 것으로 파악

취한 조치

/etc/conf.d/netmount

# 기존에 있던 설정
rc_need="net"

# 문제 해결을 위해서 추가한 부분
rc_need="net.enp1s0"
rc_need="dhcpcd"

결과

다음 시스템 시작시 확인

여기저기 찾아보다가 이런 글을 읽어보게 되었음.

Do not mix netifrc (net.*) services and dhcpcd service. They will fight for control unless specifically excluded from each other. If “net.eth0” is set to dhcp, then it starts its own copy of dhcpcd. While the dhcpcd service has another copy trying to hold control of eth0. –Grknight (talk) 14:31, 7 November 2022 (UTC)

그래서 OpenRC 기본기능으로 해보기로 하고 Dhcpcd 패키지를 다음과 같이 부팅시 제외

rc-update del dhcpcd default

결과는 아래 로그와 같음
