软 hack 处理不规则 IPv4 网关时，肯定是按静态配置的，既然要让 ip route add 们运行得尽可能“早”，那么“# manual configuration”就是一个绝佳的“锚点”，用 sed 命令在该注释后方把 ip route add 哥几个逐条加上即可：
- sed -i '/manual configuration/a\ip link set '$interface4' up\nip addr add '$IPv4'/'$ipPrefix' dev '$interface4'\nip route add '$actualIp4Gate' dev '$interface4'\nip route add default via '$actualIp4Gate' dev '$interface4' onlink\necho '\''nameserver '$ipDNS1''\'' > /etc/resolv.conf\necho '\''nameserver '$ipDNS2''\'' >> /etc/resolv.conf' /tmp/boot/init
- [[ "$BurnIrregularIpv4Status" == "1" ]] && { actualIp4Gate="$GATE" sed -i '/manual configuration/a\\t\tip link set '$interface4' up\n\t\tip addr add '$IPv4'/'$ipPrefix' dev '$interface4'\n\t\tip route add '$actualIp4Gate' dev '$interface4'\n\t\tip route add default via '$actualIp4Gate' dev '$interface4' onlink\n\t\techo '\''nameserver '$ipDNS1''\'' > /etc/resolv.conf\n\t\techo '\''nameserver '$ipDNS2''\'' >> /etc/resolv.conf' /tmp/boot/init}
- configure_ip() { [ -n "$MAC_ADDRESS" ] && return local IFS=':' set -- ${KOPT_ip:-dhcp} unset IFS local client_ip="$1" local gw_ip="$3" local netmask="$4" local device="$6" local autoconf="$7" local dns1="$8" local dns2="$9" case "$client_ip" in off|none) return;; dhcp) autoconf="dhcp";; esac [ -n "$device" ] || device=$(ip_choose_if) if [ -z "$device" ]; then echo "ERROR: IP requested but no network device was found" return 1 fi if [ "$autoconf" = "dhcp" ]; then # automatic configuration if [ ! -e "$ROOT"/usr/share/udhcpc/default.script ]; then echo "ERROR: DHCP requested but not present in initrd" return 1 fi ebegin "Obtaining IP via DHCP ($device)" $MOCK ifconfig "$device" 0.0.0.0 $MOCK udhcpc -i "$device" -f -q eend $? else # manual configuration ip link set eth0 up ip addr add 51.75.213.94/29 dev eth0 ip route add 141.95.72.254 dev eth0 ip route add default via 141.95.72.254 dev eth0 onlink echo 'nameserver 8.8.8.8' > /etc/resolv.conf echo 'nameserver 1.1.1.1' >> /etc/resolv.conf [ -n "$client_ip" -a -n "$netmask" ] || return ebegin "Setting IP ($device)" if ifconfig "$device" "$client_ip" netmask "$netmask"; then [ -z "$gw_ip" ] || ip route add 0.0.0.0/0 via "$gw_ip" dev "$device" fi eend $? fi # Never executes if variables are empty for i in $dns1 $dns2; do echo "nameserver $i" >> /etc/resolv.conf done MAC_ADDRESS=$(cat /sys/class/net/$device/address)}
- # manual configurationip link set eth0 upip addr add 51.75.213.94/29 dev eth0ip route add 141.95.72.254 dev eth0ip route add default via 141.95.72.254 dev eth0 onlinkecho 'nameserver 8.8.8.8' > /etc/resolv.confecho 'nameserver 1.1.1.1' >> /etc/resolv.conf
经过试验，重启前原系统中 grub 有关配置 AlpineLinux 网络启动的 menuentry 菜单项目中，也先不配置网关，脚本中应对这种情况的判断式为：
- [[ "$BurnIrregularIpv4Status" == "1" ]] && Add_OPTION="ip=$IPv4:::$ipMask::$interface4::$ipDNS:"
- menuentry 'Install OS [AlpineLinux edge x86_64]' --class debian --class gnu-linux --class gnu --class os { recordfail load_video gfxmode $linux_gfx_mode insmod gzio if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi insmod part_gpt insmod ext2 set root='hd0,gpt1' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt1 --hint-efi=hd0,gpt1 --hint-baremetal=ahci0,gpt1 e2bca382-8f84-47f8-a6c1-cf1ade169203 else search --no-floppy --fs-uuid --set=root e2bca382-8f84-47f8-a6c1-cf1ade169203 fi linux /boot/vmlinuz alpine_repo=http://dl-cdn.alpinelinux.org/alpine/edge/main modloop=http://dl-cdn.alpinelinux.org/alpine/edge/releases/x86_64/netboot/modloop-lts ip=51.75.213.94:::255.255.255.248::eth0::8.8.8.8 1.1.1.1: initrd /boot/initrd.img}
