Summary - dnsmasq-full breaks dnsmasq on install
Task Type - Bug Report
Category - Packages
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - Critical
Priority - Very Low
Reported Version - lede-17.01
Due in Version - Undecided
Due Date - Undecided
Details - Apologize in advance if Critical is not the correct severity for a package needed to make dnssec work.

I've used dnssec mostly successfully with dnscrypt-proxy & dnsmasq-full on Choas Calmer.  I recently upgraded to LEDE & the dnsmasq-full package fails to start dnsmasq for some reason.  Apparently I need the dnsmasq-full package to use dnssec.

At any rate, there is a new dnsmasq error message (vice Choas Calmer) on init.d restart with both the base & full package, so I'm not sure if it's relevant:
udhcpc: started, v1.25.1
udhcpc: sending discover
udhcpc: no lease, failing

I've tried resetting to the default dhcp & checked that dnsmasq.conf is basically still empty - to no avail.

What might I be doing wrong?

Supply the following if possible:
 - Steps to reproduce
1. Update to LEDE 7.01.4 (sysupgrade)
2. Install all upgradable packages
3. Install dnsmasq-full -- dnsmasq fails to load

 - Device problem occurs on:  WNDR3700v4

 - Software versions of:
