Thank you, Stéphane. It seems that I need to talk with my lab members about which cow fs is more proper.

Re: [lxc-devel] Does lxc support unionfs ?
Another question. If I start a ubuntu template lxc container tm1 and do lxc-start-ephemeral -o tm1, overlayfs mount will not include those ramfs (e.g. /proc, /sys, /run) in original container root directory, right ? Actually, I think this script run outside container tm1 and it even can't see those ramfs directories in original container. Thanks Jin 2012/6/5 Jin Chen ciccin...@gmail.com Thank you, Stéphane.

Quoting Jin Chen (ciccin...@gmail.com): Another question. If I start a ubuntu template lxc container tm1 and do lxc-start-ephemeral -o tm1, overlayfs mount will not include those ramfs (e.g. /proc, /sys, /run) in original container root directory, right ? Actually, I think this script run outside container tm1 and it even can't see those ramfs directories in original container. Yes, lxc-start-ephemeral isn't meant to be used with a running container as the original. Rather you create a pristine container, then use it only as a base for multiple ephemeral containers. Note also that if /var is btrfs, then lxc-create will automatically use btrfs snapshots for creating containers. -serge -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
