LUCI isn't deleting some entries in dhcp config when 'DHCP Client' and 'DHCPv6 Client' mode is enabled

[ShapeShifter499]

Supply the following if possible:

• Device problem occurs on
  WD My Net n750
  TP-Link TL-WDR3600 v1

• Software versions of OpenWrt/LEDE release, packages, etc.

LEDE Reboot 17.01.4 r3560-79f57e422d

• Steps to reproduce

From fresh install go to Network > Interfaces and edit the LAN interface. Switch the protocol to 'DHCP Client' and click switch protocol under 'Really switch protocol?' After it switches then click 'Save & Apply' near the bottom.

Checking the /etc/config/dhcp file after this shows some leftover settings that should have been removed but were not.

Attached are two different /etc/config/dhcp files, one labelled dhcp-incorrect.txt which is what results after preforming the above steps and another labelled dhcp-correct.txt which I believe should be the correct settings that should be applied after preforming the above steps.

Has anyone taken the time to look at this issue?

Yeah I looked at it and will fix it after the release. Since the dnsmasq init script will refuse to operate on non-static interface (https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=package/network/services/dnsmasq/files/dnsmasq.init;h=c1ae0934fd2c466687c80f7ae7f6fa567e4474fa;hb=7a6b2badfa56cfd833d64f113398198f71fd896e#l477) and since one can disable the DHCP server before switching the protocol I do not deem it release critical yet.

@jow- it's been awhile and this issue hasn't been closed. Has this been fixed for newer releases of OpenWRT and LUCI?

No, it hasn’t been fixed.
