Subject: [PATCH] resolved: create /etc/resolv.conf symlink at runtime
|
|
|
|
If the symlink doesn't exists, and we are being started, let's
|
|
create it to provie name resolution.
|
|
|
|
If it exists, do nothing. In particular, if it is a broken symlink,
|
|
we cannot really know if the administator configured it to point to
|
|
a location used by some service that hasn't started yet, so we
|
|
don't touch it in that case either.
