I'd like warn and covert the export to read-only straightly.
For example,
A test directory may be mounted many underlay filesystem (contain
ISO9660, f2fs, etc) frequently. If refuse the writeable export,
for ISO9660 the exports entry must be *(ro,...), but for f2fs
may be *(rw,...). I don't think someone wants change it every time.
thanks,
