Turns out it's unrelated to bcache; it is trivially reproducible: lxc launch ubuntu-daily:groovy g1 --vm lxc exec g1 bash fallocate -l 1024M /swap.img mkswap /swap.img swapon --verbose /swap.img cat /proc/swaps On the 5.4 kernel that groovy had a few weeks back this works, on daily (5.8) this fails: root@g2vm:/home/ubuntu# uname -r 5.8.0-18-generic root@g2vm:/home/ubuntu# fallocate -l 1024M /swap.img root@g2vm:/home/ubuntu# mkswap /swap.img mkswap: /swap.img: insecure permissions 0644, 0600 suggested.
