Exposing external Media to a 32bit chroot

Hi,
I'm using a 32bit chroot to run wine.
My problem is, that external media such as usb-sticks and drives and also cd/dvd drives don't show up in winecfg.
When I attempt to run a program off say a cd, wine complains that it cannot find the path.

I've tried symlinking /opt/arch32/etc/mtab to /etc/mtab, and running mount from within the chroot gives the same results as it does from my 'real' system. I'm guessing this has something todo with devkit, which handles external-drives and media, but I am at a loss as to how I can make wine 'see' my drives.

Any ideas??

I don't know about wine specifically, but if you mount the device outside the chroot, you should be able to bind-mount it into the chroot.

Just bind-mount /media, AFAICR.

Re: Exposing external Media to a 32bit chroot

Ohhh, ok, I see...Thanks!

EDIT: Ok, I was too fast..its still not working...
What I did was

mount --bind /media /opt/arch32/media

When I now ls /opt/arch32/media, I get the correct folders for the mounts that should be located here, but they are empty.
Also, winefile still doesn't see all mountpoints that are in /media

I'm lost!?

I think bind doesn't expose filesystems mounted under the directory you bind. according to the mount manpage you have to use this to include mounts inside the directory:

mount --rbind /media /opt/arch32/media

PS.: didn't try for myself, just citation from the manpage

Re: Exposing external Media to a 32bit chroot

Ok, thanks for that tip.
Sadly it only partly solves my problem.
Now I get all mountpoints that are in /media also in /opt/arch32/media. Also I can traverse the subdirs.
However, this only works for harddisks/partitions, not cd/dvds.
I've tried separately binding the dvd's mountpoint, without success.

EDIT:
It seems that the 'only' way I can read the contents of cd is to mount the drive directly from within the chroot env.
For my purpose of testing/installing games via wine, this is acceptable, however a more transparent solution would be nice!

Any ideas?
