[Bug 1227092] [NEW] LXC Container will not start

[Justin Shafer]

Public bug reported:

I was able to run lxc version lxc_0.9.0-0ubuntu23 with Ubuntu Touch
running kernel version 2.6.35, without AppArmor or PSTORE , without
having a mountpoint sys/fs/security (security filesystem), with a cgroup
mount at startup patch!


But with lxc version lxc_1.0.0~alpha1-0ubuntu4 I get this error starting up:

I have also had to add this manually for my fstab as update-fstab does
not find my vendor partition, nor has it mounted /system under in my lxc
container rootfs, so I added it myself.

cat /etc/fstab
# override the forced fsck from /lib/init/fstab, we use a bindmount which confuses mountall
/dev/root       /	rootfs	defaults	0	0

# swap file
/SWAP.swap		none	swap	sw		0	0
# added by lxc-android-boot for /system
/dev/dm-8	/system	ext4	ro,noatime,nodiratime,errors=remount-ro	0	0
