|

# server list. This script does not add if any of these are true:
|
||
|
|
#
|
||
|
|
# - /sbin/resolvconf does not exist
|
||
|
|
# - the systemd-resolved service is active

# - a `no-resolvconf=1` item is present in the [dns] section of lokinet.ini
|

# It always attempts to remove if resolvconf is installed (so that commenting out while running,
|
||
|
|
# then stopping still removes the added entry).
