Userspace NFSD is not something we should be considering. Disable
CONFIG_NFSD only if you're sure we never want to export stuff by NFS.

Only if we have to mount FAT file systems in any legacy character set, I
suspect.

I can well imagine ending up in situations where PPP or SLIP are needed.
Any kind of connection over cellphones or indeed phones of any kind is
likely to end up using PPP, and I believe SLIP is used with satellite
connectivity sometimes.
