@hal_pomeranz@infosec.exchange I understood that so far. But what is the point of mounting the same image with different GUIDs? Why exactly would you mount them inside of the same live system w/o assigning UUID? Volume Groups inside of LVM cannot be accessed concurrently.
I am by far no expert on data forensic examination / concurrently mounting via LVM, but this is one of the fundamentals. My guess is assigning UUID manually and rescan, so the LVM groups can be reassigned. Heck, that's in fact mindboggling.

@csem_cn@mstdn.social In the worst case scenario, you have to rename multiple layers: VG name— vgrename Volume GUIDs— vgchange -u PV GUID— pvchange -u File system GUIDs— tune2fs (EXT) or xfs_admin (XFS) You can do all of this to your working copy without impacting other data in the file system. Once all the changes are made, you can mount the images side by side. Why do you want to do this? Because each image has unique data—logs, OS changes, user data, etc. Being able to look at them side by side has value.
