This is my reproducer fwiw from the duplicate bug, LP: #2130710. It's
NOT nested LXD but two LXD containers with images with different dates
respectively in a KVM machine. The only differences I can think of
between two images are the deb versions of snapd and systemd. But
somehow, the second image doesn't install the seeded snapd.
