Hi,
I try to start an unprivileged Lxc container under Debian Sid for a
while, I tried a lot of things, but it does not work.
Futhermore, I asked here if it was a bug, but it seems not :
https://github.com/lxc/lxc/issues/414#issuecomment-71414827
Now, I'am wondering if it is not a Debian specific problem related to
some right access on /sys/fs/cgroup.
Here the ouput of systemctl status cgconfig
/hur//aira//@debian:~$ systemctl status cgconfig //
//● cgconfig.service//
// Loaded: not-found (Reason: No such file or directory)//
// Active: inactive (dead)/
Here some packages installed on my system :
/lxc 1:1.0.7-1 amd64//
//cgmanager 0.35-1 amd64//
//cgroup-bin 0.41-6 all//
//cgroup-tools 0.41-6 amd64//
//libcgmanager0: 0.35-1 amd64//
//libcgroup1:amd 0.41-6 amd64//
//libpam-cgroup: 0.41-6// amd64/
Here the log *lxc-start -n test -l DEBUG -o /tmp/lxc_test.log -f
~/.config/lxc/default.conf*:
