Lxc automatically mounts sys and proc in the rootfs of the container. When an unprivileged container is created however, the sys and proc of the host should be mounted with option relatime. The procd of openwrt mounts these with option noatime. As a result, an unprivileged container cannot start.
remounting them allows starting of the containers:
mount -t sys sys -o remount,rw,nosuid,nodev,noexec,relatime /sys
mount -t proc proc -o remount,rw,nosuid,nodev,noexec,relatime /proc
The patch modifies procd to do this correctly from the start.
Issue: LCMFT-338 for unprivileged lxc containers, proc and sys should be mounted with relatime
