I remember, while ago, container had shown the right size corresponding with
It had worked with Ubuntu free -m, with alpine /proc/meminfo.
Now to get back to that status, need to apply
lxc config set a1 security.syscalls.intercept.sysinfo=true
to each container and restart them?
sysinfo=true should actually be default, as it was the state of things before lxd version upgrades and it also delivers true information within container, which again speaks for a default situation.
