For whatever it's worth, the logic to replace or not replace
/etc/resolv.conf has gone through a bunch of adjustments, but currently,
as far as I can see it's:
if systemctl -q is-enabled systemd-resolved.service &>/dev/null &&
! systemd-analyze cat-config systemd/resolved.conf 2>/dev/null |
grep -iqE '^DNSStubListener\s*=\s*(no?|false|0|off)\s*$'; then
if ! test -e /etc/resolv.conf && ! test -L /etc/resolv.conf; then
ln -sv ../run/systemd/resolve/stub-resolv.conf /etc/resolv.conf || :
elif test -d /run/systemd/system/ &&
! mountpoint /etc/resolv.conf &>/dev/null; then
ln -fsv ../run/systemd/resolve/stub-resolv.conf /etc/resolv.conf || :
fi
fi
So, it's:
* Is systemd-resolved enabled? and is there a resolved.conf file that
does not have DNSStubListener option set to off/false/no.
* If thats the case, then is there not already a /etc/resolv.conf file and
it's not a link? ie, it doesn't exist, or it's a regular file.
Then make the link.
* Else if thats not true, then see if systemd is running at all mounting
/etc/resolv.conf from somewhere else.
So, I think if you:
disable systemd-resolved
or
make /etc/resolv.conf a real file, not a link.
or
set 'DNSStubListener=no' in /etc/systemd/resolved.conf
It will not be replaced anymore.
