you could set CacheDir to something writeable, lvs-instance-specific.
a readonly packages should be no problem at all, ro exported nfs share
is a typical setup for it.

auto tries to update the package descriptions anyways, even though you
say --nodownload, but that should be no problem, either. It might
generate a Warning, though, if there are some new descriptions on the
server.

The CacheDir must be writeable, though, even if you say "nocache",
because that only _regenerates_ the cache, it does not stop using it.
