Bug#758870: nfs-common: nfs v4: uid/gid lookup fails for some of the users

["Piet Plomp" <pietplomp@xs4all.nl>]

Hi Ben,

Here are some tests:

A wheezy system:
    For a new test I took a standard _wheezy_ system without systemd,
    3.2.0-4 kernel (Debian 3.2.60-1+deb7u3). No nfs problem.

    I upgraded libc6 to jessie's 2.19.9: no nfs problem.

    Then I installed the linux-image-3.14.2-amd64 (3.14.15-2) kernel
    (which pulled in initramfs-tools) and rebooted: : YES there is
    the nfs problem!

A jessie system:
    Another system, one of the jessie systems with older kernels installed:
    - kernel 3.13.10  nfs problem YES
    - kernel 3.14.12  nfs problem YES
    - kernel 3.14.15  nfs problem YES
    - kernel 3.2.0-4 (3.2.54 from wheezy) nfs problem NO
    This system uses systemd.

Looks like it's a kernel problem, the problem is not introduced in 3.14.11
or 12, as I thought earlier.

This libc version cannot be correct. But it is one of the 2.19 series, and
the problem still exists in 2.19.9.
