[pkg-cryptsetup-devel] Bug#509068: cryptsetup: improve passdev, that it also works when the device is already mounted

[Christoph Anton Mitterer]

Package: cryptsetup
Version: 2:1.0.6-6
Severity: wishlist

Currently,... when passdev is given a device:path where the device is  
already mounted somwhere it fails.

It would be nice that it doesn't fail in this case but bind-mount the  
device readonly.
This would also be important I you agree my following proposals where  
I ask if we could change cryptsetup, that all keyscripts should/must  
support device:path-syntax (see also this thread  
http://lists.alioth.debian.org/pipermail/pkg-cryptsetup-devel/2008-December/002376.html)

I'm not sure if this works when the device was originally mounted rw,  
but I think it does.
I'd also suggest to do the bind-ro-mounting instead of just reading  
the file, because this would change access time which is perhaps  
monitored or have other influences on a rw-mounted filesystem.

I think I'd need help with these changes ;)

Thanks,
Chris.
