The manpage /usr/share/man/man8/rpc.rquotad.8.gz is a link to rquotad.8.gz (or quotad.8.gz I forgot) BUT the latter is in another package, which need not be installed---> thus the former is an undefined link. The upshot is that everytime cron runs makewhatis it sends an e-mail to root saying it did not find that file.

Observation, adding to the spec file: rm %{buildroot}/%{_mandir}/man8/rpc.rquotad* around line 77 in the %install section, appears to cure this problem. Obviously the analagous change is needed in the quota package Julian King Computer Officer, University of Cambridge, Unix Support
All of the rquotad man pages are now removed during the nfs-utils install.
