Bug#323107: xserver-xorg: -config and -xf86config options differ

["Mario 'BitKoenig' Holbe" <Mario.Holbe@TU-Ilmenau.DE>]

Package: xserver-xorg
Version: 6.8.2.dfsg.1-5

Hello,

while migrating from XFree86 to X.org, I tried to replace the
-xf86config option via -config which, according to X -help,
should do the same (although X.org does understand -xf86config, it's not
documented).
Surprisingly, `startx -- :1 -xf86config xorg.conf -nolisten tcp' works
as expected, while `startx -- :1 -config xorg.conf -nolisten tcp' does
not:

X: warning; nice() of process failed: Permission denied
X: warning; process set to priority -1 instead of requested priority -10

Fatal server error:
Cannot move old log file ("/var/log/Xorg.1.log" to
"/var/log/Xorg.1.log.old"


Please consult the The X.Org Foundation support
         at http://wiki.X.Org
 for help.

giving up.

It seems as if -config releases privileges too early while -xf86config
does not.

This is probably something to be forwarded upstream.


Thanks for your work & regards
   Mario
