If you want to check if the mount point is > effectively setup, you should check against /proc/mounts. Unfortunately it looks like /proc/mounts provides the same info as the mount command for me - /dev/mapper/fridge-srv / ext4 rw,relatime,barrier=1,data=ordered 0 0 none /dev/console\040(deleted) devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000 0 0 none /dev/tty1\040(deleted) devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000 0 0 none /proc proc rw,nosuid,nodev,noexec,relatime 0 0 none /sys sysfs rw,nosuid,nodev,noexec,relatime 0 0 none /sys/fs/fuse/connections fusectl rw,relatime 0 0 none /sys/kernel/debug debugfs rw,relatime 0 0 none /sys/kernel/security securityfs rw,relatime 0 0 none /dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000 0 0 none /dev/shm tmpfs rw,nosuid,nodev,relatime 0 0 none /var/run tmpfs rw,nosuid,relatime,mode=755 0 0 none /var/lock tmpfs rw,nosuid,nodev,noexec,relatime 0 0 none /lib/init/rw tmpfs rw,nosuid,relatime,mode=755 0 0 So the entries from the lxc.mount fstab: /srv/vm/lxc/lemon/rootfs /srv/vm/lxc/rootfs none bind 0 0 /var/cache/apt /srv/vm/lxc/lemon/rootfs/var/cache/apt none bind 0 0 do not appear to be effective. I tried creating the file in /var/cache/apt of the container and it did not appear in the host filesystem so it looks like they are really separated. Is there anything that can be done to debug this problem? And even more interesting, is there anybody else experiencing such kind of issue?
