Subject: trans/fakeroot: override fshelp_isowner
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As of recently, fakeroot would fail to create symlinks:

% fakeroot-hurd ln -s foo a
ln: failed to create symbolic link ‘a’: Operation not permitted

Fix this by overriding fshelp_isowner.

Various netfs functions will call fshelp_isowner to check whether USER
is allowed to do some operation.  As fakeroot is not running within
the fakeauth'ed environment, USER contains the real user.

I have no explanation why this ever worked.

* trans/fakeroot.c (fshelp_isowner): New function.
