Subject: man/man7/mount_namespaces.7: Fix an incorrect path in an example
X-Git-Tag: man-pages-6.12~5
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4b307134ee68cd0f3568a3d2d9c2119bd5a8adf6;p=thirdparty%2Fman-pages.git

man/man7/mount_namespaces.7: Fix an incorrect path in an example

In the example showing how locked mounts in a less privileged mount
namespace can not be split, first </etc/shadow> is bind mounted, then an
attempt is done to unmount </mnt/dir>, which gives an error complaining
that </etc/shadow> is not mounted.  The unmount should also refer to
</etc/shadow>.

Fixes: 906ab4945cd3 (2021-08-20; "mount_namespaces.7: Rewrite locked mounts examples to use/etc/shadow")
Closes: <https://bugzilla.kernel.org/show_bug.cgi?id=217709>
