The script /etc/rc.d/init.d/nfs in the nfs-utils package (version 0.3.1-8)
tries to run rpc.rquotad. However, if the "quota" package isn't installed
(e.g., because the server has no need for quotas), rpc.rquota doesn't
exist. There probably needs to be a sysconfig variable somewhere that
controls whether or not quotas are in use -- installing the "quota" package
should cause this variable to be set, and uninstalling it should cause the
variable to be unset, automatically.
This will be fixed in the next release.
