Thanks for your response .. however, I', still puzzling with lxc.
- In stock 17.01 (rc2) there are packages lxc-cgroup, lxc-execute.
- But from my understanding linux cgroup may be missing, causing
lxc-execute to fail:
root at Node-2:/rom# lxc-execute -n test /bin/sh
lxc-execute: start.c: must_drop_cap_sys_boot: 583 failed to clone
(0x20000012): Invalid argument
lxc-execute: cgfs.c: cgfs_init: 2246 cgroupfs failed to detect cgroup
lxc-execute: start.c: lxc_spawn: 948 failed initializing cgroup support
lxc-execute: start.c: __lxc_start: 1192 failed to spawn 'test'
Intuitively, I expected lxc-cgroup to depend on sth. like kmod-cgroup,
but there's no such thing.
Did you recompile lede? I need to do this with lede (stock).
For those of you without hope, we have rooms with color TV,
cable and air conditioning
