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

[Bert Hutzler]

uuhhh, probably someone repaired this to bits.
I did a nfs mount using the leading slash (wondering what may be on so.'s mind to omit it???),
and got into exatly that problem, OS stating "not found in /proc/mounts", because of different entries there and in /etc/mtab.
But in my case there are two slashes in /proc/mounts!!!
uname -a:
Linux ubuntubert 3.2.0-88-generic #126-Ubuntu SMP Mon Jul 6 21:33:03 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Although I could unmount editing /etc/mtab, this is a bug and should be
fixed.
