題目: [DNG] hijacking resolv.conf - possible fix?
Hello:

Users of [connman] and [network-manager] (and possibly maybe other
such applications) who want to run their boxes with their own DNS
settings know exactly what I am referring to in the subject title.

I was one of them till I decided to go the [ifupdown] route and rid
myself of both the headache and a layer of abstraction.

Then, while searching on how to fix something else, I came across
[/sbin/dhclient-script] and within it, this bit which instantly
called my attention:

[code]
--- snip ---
# update /etc/resolv.conf based on received values    # <---- wthf?
  make_resolv_conf() {
      local new_resolv_conf
--- snip --- 
[/code]


Not in any way script savvy but it seemed I had found the hijacker,
so to speak.

Those who know more could confirm my suspicions.

According to [jed], the whole snippet is from line 39 to line 125 and
it would seem (?) to be the routine that constantly overwrites
[/etc/resolv.conf] just because some idiot thought it was a good idea
to do so.

The web is full of posts complaining about this issue from quite a
few years back, all of which have been ignored.

But I digress ...

I was wondering if this could be put to death without much ado or
causing extra work for the Devuan maintainers.

Maybe a small / specific Devuan meta-package with a script to edit
[/sbin/dhclient-script] and bring some peace to independent DNS
users.

Just a thought.
Opinions/solutions welcome.

Best,

A.
