create ioctl on diskimage failed: Device or resource busy

[Claxl]

Issue Summary

I'm experiencing two errors when attempting to build the Linux vanilla sd_card.img using colcon on my workstation. These errors occur under different conditions:

• First Execution after Booting:
  • Error message: mount: /tmp/sdcard_img_p1: overlapping loop device exists for /home/claudio/krs_ws/acceleration/firmware/kv260/sd_card.img.
  • Outcome: The sd_card.img is generated correctly, but this error appears.
• Subsequent Executions:
  • Error message: device-mapper: create ioctl on diskimage failed: Device or resource busy. Command failed.
  • Outcome: The command fails to create the sd_card.img on subsequent attempts after the initial successful build.

Environment

Host OS: Ubuntu 22.04 (on a partitioned SSD)
Working Directory: ~/krs_ws
Command: colcon acceleration linux vanilla --install-dir install-kr260
Using: KRS

Second Error:

More info on my env:

 ROS2` humble
 rmw_cyclonedds as DDS

I have followed the KRS setup tutorial and the KR260 workaround.
My question are:

Is it still possible to use the sd_card.img?
Is there a workaround for not rebooting every build?
