Memory Cgroup

[dropchew]

Not sure if this was asked previously.

After successfully flashing UB on pixel 2 XL, ssh in

1. Notice there's no memory cgroup?
   Reason for this ask as I am trying a poc to create chroot via debootstrap and in chroot , running arm64 k3s binary directly (systemd will not work) and it throwing error that it can't find memory cgroup.

2. trying cifs mount and throwing the below error. We can't do a smb mount in ubuntu touch?

mount error: cifs filesystem not supported by the system
mount error(19): No such device
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs
