Where can I add --noatime to my lxc containers?

[FrankB]

Since the /etc/fstab should not be edited in the Containers, I'm assume I can do this through one of the LXC config files.

Does anyone know which ones I need to edit to add --noatime to the drive parameters.

This should increase my IO performace, I hope.

I think I discovered in the LXC docs that ever since V1 you can add

lxc.rootfs.options = noatime

to /var/lib/lxc/100/config

So I think I got this taken care of.

This is better than sliced bread. I went from 12% Disk I/O utilization at non-peak hours to 00.01% at non-peak. Do not do this on your mail servers, as most use the last access times for archiving and other purposes.

Crap, when the config file gets regenerated, the parameter gets removed. Where can I make it part of the template and persistent.
