Title:
  build nfsdcld to avoid grace period in containers

Status in nfs-utils package in Ubuntu:
  Fix Released

Bug description:
  Trying to use kernel nfs server in containers generally works, but
  generates dmesg warnings as follows:

  [   23.392559] NFSD: attempt to initialize umh client tracking in a container ignored.
  [   23.395065] NFSD: attempt to initialize legacy client tracking in a container ignored.
  [   23.395085] NFSD: Unable to initialize client recovery tracking! (-22)
  [   23.395106] NFSD: starting 90-second grace period (net f00005fd)

  On reboot clients do indeed hang for the grace period.

  From the description here ..

  https://man7.org/linux/man-pages/man8/nfsdcld.8.html

  .. it seems that modern kernels in combination with nfsdcld from
  modern nfs-utils can avoid this problem - is there any chance we could
  build and install it? It looks like it might have a sqlite dependency
  so possibly needs splitting off into a separate package.
