/dev/loop0 after install image?


Coming from long stable use of VyOS 1.1.7, I have to update to the new 1.2 due to needing to install an updated open-vm-tools required by host (for mitigation of Spectre/Meltdown). I created an image, had hosting provider mount the ISO (problems on their end prevent end-user mount) did an ‘install image’, had the hosting provider unmount the disk. However, after boot, ‘df’ looks like this:

Is the loopback expected to be there after image install and dismount of ISO? My legacy VyOS has no /dev/loop0 in normal running.


Found my own answer by firing up a local VM in Parallels. The /dev/loop0 is a normal part of the running system even after ISO is detached.
