The attachment works fine, you just have to run "chmod +x strace" before you run the binary. That marks it as executable.
Thanks for the output, but you should run
Code:
strace mount /dev/loop0 /mnt/user
instead of loop1. That's why it says that it's an I/O error. As the strace log you provided showed that losetup set it up at /dev/loop0, you have to mount /dev/loop0, not loop1.
Reboot and retry
