Gnu tar dosn't honour --one-file-system option.

[Malcolm Kay]

While backing up a FC6 system Gnu tar fails to honour
the --one-file-system option with respect to cifs 
shares mounted from a MS server.

There is no problem with other file systems such as for example
/boot and /sys.

A partial work around is to use --exclude mountpoint for each
cifs mount point but this depends on knowing all the cifs mount 
points in use.

Does anone else see this problem?

Is there a real fix?

Any assistance appreciated:
