Hi, guys.
I'm using 1.0.0.alpha1 although I've tried with 0.8.0 also and I'm
unable to start container with the following error:
lxc-start: Invalid argument - pivot_root syscall failed
lxc-start: failed to setup pivot root
lxc-start: failed to set rootfs for 'repos'
lxc-start: failed to setup the container
lxc-start: invalid sequence number 1. expected 2
lxc-start: failed to spawn 'repos'
I've tried mount --make-private on all mount point I've thought of with
no luck.
Also I've tried lxc.autodev = 1 also no luck and I guess this is
relevant with systemd while this systems uses openrc as init system.
Container's conf file:
lxc.arch = amd64
lxc.utsname = repos
lxc.rootfs = /virt/lxc/repos
Distribution Gentoo. Same config works fine on another gentoo system.
Although systems are completely different I think important differences
are:
1. init system: on laptop I'm using systemd while on server openrc
2. on server I have full system inside ram (system resides inside
initramfs and after boot root stays in RAM on rootfs)

So any suggestions are welcome. Output of -l DEBUG -o test.debug in

Just for record, I've opened bug report
https://github.com/lxc/lxc/issues/61 for this.
TIA,
