[Bug 2059197] [NEW] Issue with nfs4.0 mounts after upgrade to 3.6

[Jeff]

Public bug reported:

Hello,

On Ubuntu Server 20.04.6 LTS with the update of nfs-common package =>
"nfs-common/focal-updates 1:1.3.4-2.5ubuntu3.5" to "nfs-common/focal-
updates 1:1.3.4-2.5ubuntu3.6" I started having issues mounting ntf4.0
volumes. The NFS server supports 4.0, 4.1 and 4.2

The issue appears when using '-t ntfs4' and setting the version using -o
vers=.

When using 1:1.3.4-2.5ubuntu3.5 I am able to use '-o vers' to set the version when using -t ntfs4 eg
  mount -t nfs4 -o vers=4.0 -vvv SERVER.local:/srv/data /mnt/test
    mount.nfs4: trying text-based options 'vers=4.0,addr=xx.xx.xx.xx,clientaddr=xx.xx.xx.xx'  

  mount -t nfs4 -o vers=4.1 -vvv SERVER.local:/srv/data /mnt/test
    mount.nfs4: trying text-based options 'vers=4.1,addr=xx.xx.xx.xx,clientaddr=xx.xx.xx.xx'  

However after upgrading to 1:1.3.4-2.5ubuntu3.6 it always mounts as nfs4.2
  mount -t nfs4 -o vers=4.0 -vvv SERVER.local:/srv/data /mnt/test
  mount.nfs4: trying text-based options 'vers=4.2,addr=xx.xx.xx.xx,clientaddr=xx.xx.xx.xx'  

  mount -t nfs4 -o vers=4.1 -vvv SERVER.local:/srv/data /mnt/test
  mount.nfs4: trying text-based options 'vers=4.2,addr=xx.xx.xx.xx,clientaddr=xx.xx.xx.xx'

I would have expected the specified version in -o vers to be used when
using '-t nfs4'

When using '-t nfs' I am able to mount volumes as nfs 4.0. I understand
that 1:1.3.4-2.5ubuntu3.6 fixes version negotiation so maybe this isn't
a bug and the intent with '-t nfs4' is to always use the highest
version. If so please feel free to close the report
