Root Kernel- Loop Device support

Typical use of a loop device is to attach a virtual node in unix.

If you caught my posts last year on running Ubuntu in parallel with Android on my phone, I did that by getting an image file of Ubuntu and assigning it to a loop device.

I am in awe of the things people know how to do. I didn't even know they existed, let alone how the work, or how to do them.

Nice seeing you outside of the LTEvo forums. ;)

How would I do that? Also I'm trying yo run BackTrack, would it be the same procedure?
When I try to boot it I get these errors, and I'm not sure what I'm doing wrong. I know it says BackTrack ARM for Xoom but its modified to work on all,

Bad news, they knew how to do it right.

They check to see if the loop device target exists (in use) before proceeding and give an error message if that happens. So they don't assume a free slot, in other words.

That passes and they use the shorter command sequence and handle it through a mount -o call. So while they don't do an explicit losetup, they don't need to, it's kernel limited as you thought.

I guess maybe your next move would be to ask kernel devs working this device to add the feature for you.
