[Bug 974374] Re: Error on unmounting a NFSv4 share

[WIll Salmon]

We get this problem on servers 12.04.5 running Trusty kernel
3.13.0-65-generic (and on 12.04.4 running Quantal kernel 3.5.0-54 )

/etc/fstab has a slash at the start of the NFS server path

/proc/mounts has an unnecessary extra "/" on the NFS path: like this :-

nfs-server://home/users /export/home/nfshomes nfs4 .....

whereas  /etc/mtab correctly does not ...

nfs-server:/home/users /export/home/nfshomes

This is a nasty bug in a basic utility (umount.nfs) and really should be
fixed !!
