Hello DNS Masq,

While using dnsmasq as part of libvirt I've noticed that my /etc/hosts prevents my VMs from starting. I looked through the system logs and found that it was DNS Masq that was crashing causing my VMs to not have any network (not even DHCP or any ip connectivity).

I'm using NixOS and using StevenBlack hosts to block ads on my system.

I sorted /etc/hosts lines by length and then performed a binary search to cut down the longest lines one by one.

What I found was that once the lines get to <=57 chars dnsmasq is able to start with no problems.

Please see my change log here for what I've done on my system:

Why do you deliberately and repeatedly misspell dnsmasq as DNS Masq?
