Hullo!

Had a spare minute to try my new shiny kernel, now sporting the 
cream of 1980s file sharing:

  ~ λ grep ^CONFIG_NFS /run/current-system/kernel/.config 
  CONFIG_NFS_FS=m
  CONFIG_NFS_V3=m
  CONFIG_NFS_FSCACHE=y
  CONFIG_NFS_DISABLE_UDP_SUPPORT=y
  CONFIG_NFS_COMMON=y

Much less than Guix's linux-libre package enables by default, but 
it should suffice -- I think?

For now:

  # With ‘mount’ patched to look in /run/setuid-programs:
  ~ λ sudo mount -t nfs 1.2.3.4:/ /mnt
  mount.nfs: Protocol not supported

OK, I'm obviously missing an NFS server to actually test, but 
maybe it works now?

Be sure to pull before testing as I fixed a different bug in 
nfs-utils on master.

Kind regards,

T G-R
