Hi all,
I've a question about this command.
Let's take a simple test:
$ touch foo
$ echo foo > foo
$ touch bar
$ mount --bind foo bar
$ cat bar
foo
$ umount foo
On some files system/distribution/kernel, the last command returns an error
(on debian for example):
$ umount foo
umount: foo: not mounted
or unmount bar (on ubuntu for example):
$ umount foo
$ cat bar
$
I did not find the reason of this difference, any help is welcome.
Thank you,
Nicolas
