For my problem, it is a crypted datadir for a backup server, not a rootfs. I wanted to use /var/lib/lxc/container/fstab to have the block device mounted at lxc startup whitout use any wrapper around lxc-start. For my education, is there any differences between these two solutions : - using /var/lib/lxc/container/fstab - mknod in the container + use his /etc/fstab Regards, Guillaume ZITTA ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
