Bug#867067: create directory for nfsdcltrack

[Elimar Riesebieter <riesebie@lxtec.de>]

Control: found -1 1.3.4-2.5
Control: severity -1 grave

Hi all,

this bug causes kernel panics at least on i386 and x86-64 running
nfsv4 servers so set severity to grave.

I can confirm that the above workaround doesn't cause kernel panics
anymore.

Thanks
