Comment 8 for bug 44836

NFS mounts *are* sometimes not actually mounted. NFSv4 mounts seem to be more often missing than not. After reboot:

pieter@danae:~$ grep : /etc/fstab
# /etc/fstab: static file system information.
repo:/aegis /aegis nfs4 rw,rsize=32768,wsize=32768,defaults 0 0
pixar:/net/pixar /net/pixar nfs rw,tcp,rsize=32768,wsize=32768,defaults 0 0

pieter@danae:~$ grep : /proc/mounts
pixar:/net/pixar /net/pixar nfs rw,v3,rsize=32768,wsize=32768,hard,lock,proto=tcp,addr=pixar 0 0

pieter@danae:~$ sudo mount -a
pieter@danae:~$ grep : /proc/mounts
pixar:/net/pixar /net/pixar nfs rw,v3,rsize=32768,wsize=32768,hard,lock,proto=tcp,addr=pixar 0 0
repo:/aegis /aegis nfs4 rw,v4,rsize=32768,wsize=32768,hard,intr,lock,proto=tcp,addr=repo 0 0

But if I re-order the NFSv4 mount after the NFSv3 mount, it *was* mounted 6 reboots in a row.
