Hi John,
I routinely have dnsmasq running on my Devuan ASCII box (was running
Debian testing/jessie before) and never observed any irregularities.
I checked and the PID file is correctly maintained, issuing service
start/stop/status commands works as expected. (dnsmasq 2.76-5+deb9u1)
For comparison I tested again on a Devuan Jessie VM (dnsmasq version
2.72-3+deb8u2, same as yours) with identical positive results. No
resolvconf installed on both systems.
The dnsmasq init scripts in Jessie and ASCII differ basically just in
the relocation /var/run --> /run. But since the former should be just
a symlink to the latter on both systems it should not have any
noticeable effect at all. For reference I attached a diff between the
two versions.
Whatever causes you trouble, I strongly believe it's not the dnsmasq
init script per se that is to blame.
Sorry I cannot provide you with an instant solution for your problem.
HTH, best regards
Urban
P.S.:
Yes, I too find the file time stamps in the diff slightly irritating,
but I double checked I was comparing the correct files. I did not
inspect the respective source packages though.
