Comment:
Thanks ericonr!

Adding

```
cgroup_memory=1 cgroup_enable=memory
```

to cmdline.txt actually fixes the issue:

```
bash-5.0# uname -a
Linux pimpel 5.4.59_1 #1 SMP Wed Sep 2 20:17:25 UTC 2020 armv7l GNU/Linux
bash-5.0# mount|grep mem
cgroup on /sys/fs/cgroup/memory type cgroup (rw,relatime,memory)
```

So looks like void is not at fault here and that the kernel defaults just changed (for machines with 'low' amounts of RAM)
