Dear List,

This evening, I tried to upgrade my LTSP server to 5.2 with Debian
backports.

After upgrading the server, I've created a new chroot, with the
backports too, as stated in

 http://wiki.debian.org/LTSP/Howto/Lenny-With-Backports 

giving this output to ltsp-info[1].

But the localdevs only work to some extend :

- CD/DVD doesn't work at all (nothing happens on pluging
  drive/inserting media/removing/etc) ;

- USB devices are mounted in /tmp/.<user>-ltspfs/<device> ;
  corresponding mountpoints are created in /media/USER/DEVICE ; but
  the bind to there is never done.

  (Note : devices are working normaly in /tmp though : I'm able to
  write/read files on them).


So, it seems to be a mix of this problem :

http://marc.info/?l=ltsp-discuss&m=127748050031089&w=2

(but I do have the Debian backports...)

with this one :

http://marc.info/?l=ltsp-discuss&m=127229280518590&w=2

(but I've tried Vagrant's suggestions to no avail...)


If I follow the Ubuntu DebugLocalDev, all is fine until the last step,
where the command shows this error message :

suid mount failed: [Errno 16] Device or resource busy: '/tmp/.jfs-ltspfs/tmp'


"/tmp" of the TC is mounted in /tmp/.jfs-ltspfs/tmp though ; a
directory to receive it is created in /media/jfs, but the operation
fails to bind the content of the first in the last (as I understand,
the mount in /tmp should only be temporary).


I've tried to upgrade fuse-utils/libfuse2 on the server (backports)
just in case, but with no better results regarding localdev.

After re-reading all related posts on the list since 5.2, I run out of
ideas and I'm at the point where I must ask for some help...

So, does anyone have a hint ? Or in other words, what can be the
reasons for a mount in /tmp to not bind to /media/USER ?


I know that's very strange since problems with 5.2 seem to be very
low, but I can repeat the problem to no end, with differents users and
usb devices.

Many thanks in advance (and, by the way, thanks also in general to the
LTSP devs for their work) !
