fail to mount nfs4

[Léa GRIS]

Trying to mount nfs4 shares fail with:

mount -t nfs4 -o sec=krb5 nfsserver.lan:/ /mnt/nfsv4
mount: wrong fs type, bad option, bad superblock on nfsserver.lan:/,
       missing codepage or other error
       In some cases useful info is found in syslog - try
       dmesg | tail or so

Strace mount reveal a failed stat of /sbin/mount.nfs4:

stat64("/sbin/mount.nfs4", 0xbfd8015c) = -1 ENOENT (No such file or
directory)
rt_sigprocmask(SIG_BLOCK, ~[TRAP SEGV RTMIN RT_1], NULL, 8) = 0
mount("nfsserver.lan:/", "/mnt/nfsv4", "nfs4",
MS_POSIXACL|MS_ACTIVE|MS_NOUSER|0xec0000, 0x805ac98) = -1 EINVAL
(Invalid argument)

Note: the original reporter indicated the bug was in package 'nfs-client'; however, that package was not published in Ubuntu.
