Bug#568074: Acknowledgement (Xfbdev: LinuxInit: Server must be suid root)

["Trent W. Buck" <trentbuck@gmail.com>]

PS: I just noticed that /usr/bin/X isn't an update-alternatives link
to /usr/bin/Xorg, as I had previously assumed.  It turns out that

    $ xinit -- /usr/bin/X

works, but

    $ xinit -- /usr/bin/Xorg
    Fatal server error:
    Cannot move old log file ("/var/log/Xorg.0.log" to "/var/log/Xorg.0.log.old"

I presume this is because /usr/bin/Xorg is also not setuid.

It occurred to me that maybe I am expected to say something like

    $ xinit -- /usr/bin/X --real-binary-is /usr/bin/Xfbdev

but the non-Xorg-specific options to /usr/bin/X don't appear relevant:

    $ diff -u <(Xorg -help 2>&1) <(X -help 2>&1)
