But "nfs" is exported via kldxref and should be loadable via "kldload nfs".
Secondly, this is why I did not remove nfsiod to start with. I was planning
to redo it as a wrapper that did the module load, and emulated the arguments
by translating them into a sysctl to set the number of kernel nfsiod's
and then exiting. This would solve the ordering problem entirely
and wouldn't depend on actually having nfs file systems in fstab in order
to set the sysctl's.
Cheers,
