<PRE>Juergen Harms skrev 30.11.2012 19:48:
&gt;<i> I am having problems with utility programs that do serial I/O and use
</I>&gt;<i> locks in /var/lock/tty (and they often require group ownership of this
</I>&gt;<i> directory to be dialout (back in the past it was tty).
</I>&gt;<i>
</I>&gt;<i> In the past, it was sufficient to create /var/lock/tty after system
</I>&gt;<i> generation. In Mageia 3 /var/lock/tty now disappears at each reboot,
</I>&gt;<i> which breaks the locking facility of these programs (in Mageia 3
</I>&gt;<i> /var/lock/ is a link to /var/run, which in turn links to /run)
</I>&gt;<i>
</I>&gt;<i> Is this design, a bug, a consequence of the run-dir support that comes
</I>&gt;<i> with Mageia 3? I guess it is the last. What can be done to make these
</I>&gt;<i> programs work again (they run at user level and do not have the
</I>&gt;<i> priviledges to, at run-time, create /var/lock/tty with the correct
</I>&gt;<i> ownership)?
</I>

Add a /etc/tmpfiles.d/&lt;app_name&gt;.conf

with the contents:
d /run/tty 0775 root dialout -
