Unfortunately symlinks (from
vgpu-manager/rhel8tovgpu-manager/rhel9) would not cut it, as we pass the subdir, making those files (insiderhel8unreachable from any other sibling folder).Let me see if I can come up with a cleaner way, rather than duplicating all the files in
vgpu-manager/rhel*There was a problem hiding this comment.

It seems most directories do indeed have copies of the same files, so I'll leave the duplicates inside
vpu-manager/rhel*folders instead of refactoring.
