<i>&gt; &gt; Another thing: When using xscanimage with suid root to get access</i><br>
<i>&gt; &gt; to the port, it seems that file ownership for the output files created</i><br>
<i>&gt; &gt; also defaults to root. This is sometimes annoying, although not serious.</i><br>
<i>&gt; </i><br>
<i>&gt; Is it still the case with 0.74 ? I think I had to remove the</i><br>
<i>&gt; file /tmp/out.pnm as root before being able to scan into that file,</i><br>
<i>&gt; but may be I have missed to set the mode 4755 before doing this...</i><br>
<i>&gt; </i><br>
<p>
Why on earth would you want to run xscanimage setuid root? This is an<br>
aweful practice in my opinion. Why not just set read/write permissions<br>
on the /dev/device?<br>
<p>
Am I missing something?<br>
