Why are some NFS mount options like intr/nointr and bg/fg missing when checking with the mount command?

Solution In Progress - Updated -

Issue

  • Mounting an NFS share has the following options.
rw,intr,bg,hard,timeo=600,wsize=32768,rsize=32768,nfsvers=3,tcp,nolock
  • But. when parsing the mounts, some of the mount options do not show up.
(rw,relatime,vers=3,rsize=32768,wsize=32768,namlen=255,acregmin=0,acregmax=0,hard,nolock,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=*.*.*.*,mountvers=3,mountport=1234,mountproto=tcp,local_lock=all,addr=*.*.*.*)
