Some checks are pending
Build Kernel / Build all affected Kernels (push) Waiting to run
Build all core packages / Build all core packages for selected target (push) Waiting to run
Otherwise odhcpd logs:

```
odhcpd[14970]: Sent 113 bytes to xxx%lan@br-lan
BusyBox v1.37.0 (2025-10-10 09:07:48 UTC) multi-call binary.

Usage: basename FILE [SUFFIX] | -a FILE... | -s SUFFIX FILE...

Strip directory path and SUFFIX from FILE

        -a              All arguments are FILEs
        -s SUFFIX       Remove SUFFIX (implies -a)

Apparently procd scripts expect initscript set.

cdb9e5b odhcpd: improve RFC9096 § 3.5 SLAAC compliance

RFC9096 § 3.5 SLAAC compliance introduces a new config option (odhcpd
piofolder), which may wear out the flash under certain conditions (for
example: ISPs with dynamic IPv6 prefixes which disconnect the clients
every X hours).
Therefore, setting "dhcp.odhcpd.piofolder" to persistent storage in the
router flash is not advisable and should be set to other kinds of
persistent storage such as USBs, SDs, NVMEs...
In order to prevent wearing out the router flash it's set to ephemeral
storage by default (tmp):
  uci set dhcp.odhcpd.piofolder="/tmp/odhcpd-piofolder"

odhcpd: setup dhcpv4 server automagically
Automatically setup dhcpv4 server just like it's done for dhcpv6.
To select whether odhcpd or dnsmasq are serving DHCPv4 requests there
still is the 'maindhcp' option. To make things less confusing, make
sure things really work out-of-the-box in case dnsmasq is not even
installed at the time the uci-defaults script is being run.

ae57675bba odhcpd: don't enable server mode on non-static lan port
Instead of blindly enabling the odhcpd v6 server and RA server on the
lan port, only do that if the lan port protocol is "static"

This prevents the unhelpful case of a device being a dhcpv4 client and
v6 server on the same ethernet port.
