Interesting point.  As /var/run/NetworkManager/resolv.conf still
exists after stop, it would be OK.  But if the machine is then
rebooted with network-manager still disabled, the problem resurfaces.

Question: If the symlink is reverted to an empty file on stop, but the
/var/run version is kept intact, would NM pick it up again on restart,
just by recreating the symlink?  Or does NM recreate the /var/run
version on startup anyway?  If either of these are the case, then it
seems that it would be fine to revert /etc/resolv.conf on stop, as it
should have no bad effects (and possibly some good ones).

Incidentally, it seems as though NM obliterates any previously
existing resolv.conf when it is first run, so there is no hope of
reinstating the previous version.  This does not seem ideal, either.

Best wishes, and thanks for your quick response.
