[BUG]: Default gateway not always set via DHCP

[bryanward-net]

What happened?

dhclient.conf is requesting the rfc3442-classless-static-routes option from the DHCP server.
This causes a default gateway route to not always be installed if the DHCP server is responding with this option

Relevant log output

No logs.

How often does this bug happen?

Sometimes

What version are you using?

3.1.4-rc1 and possibly later

Where is the bug located?

pi-gen/wlanpi1/01-config-files/00-run.sh

Line 14 in ad762cc

Need to patch /etc/dhcp/dhclient.conf to look like:

request subnet-mask, broadcast-address, time-offset, routers,
        domain-name, domain-name-servers, domain-search, host-name,
        dhcp6.name-servers, dhcp6.domain-search, dhcp6.fqdn, dhcp6.sntp-servers,
        netbios-name-servers, netbios-scope, interface-mtu,
        ntp-servers;
#       rfc3442-classless-static-routes, ntp-servers;

to remove the rfc3422-classless-static-routes option

This is addressed as requested. Same code verified in pi-gen-bookworm lite image for the WLAN Pi Go tracked by WLAN-Pi/pi-gen-bookworm#19.

wlanpi@wlanpi-a4c:/etc/dhcp $ head dhclient.conf -n 21
# Configuration file for /sbin/dhclient.
#
# This is a sample configuration file for dhclient. See dhclient.conf's
#       man page for more information about the syntax of this file
#       and a more comprehensive list of the parameters understood by
#       dhclient.
#
# Normally, if the DHCP server provides reasonable information and does
#       not leave anything out (like the domain name, for example), then
#       few changes must be made to this file, if any.
