Subject: bug#7274: tail-2/F-vs-missing failure on RHEL 5.5 x86-64 + NetApp filer
Date: Sat, 23 Oct 2010 18:39:11 -0700

I got the following failure when running "make test"
on RHEL 5.5 x86-64 when the build directory is served
from a Network Appliance filer.  I'm no expert in what
"tail" is supposed to do here, but a casual look at the
output makes it appear that it might just be a bug in
the test program.  The filer does suffer from minor
clock skew with respect to the RHEL client.

FAIL: tail-2/F-vs-missing (exit: 1)
